I’ve been reading more pdfs in my phone lately using the books app but was pretty disappointed in its features set for an app that supposedly specializes in reading.

I’m looking for a third party iOS app to read pdfs that allows me to change the font size of pages and also invert the pages Color’s from white page to black and text to white. Also I especially don’t want any data collected and no ads.

I thought you guys would know best any suggestions? Thank you

Side note: There was an incredible open source pdf viewer on android called MJ pdf, wish it was available on iOS

"Many members of the mainstream scientific community react with extreme hostility when presented with certain claims. This can be seen in their emotional responses to current controversies such as UFO abductions, Cold Fusion, cryptozoology, and numerous others. The scientists react not with pragmatism and a wish to get to the bottom of things, but instead with the same tactics religious groups use to suppress heretics: hostile emotional attacks, circular reasoning, dehumanizing of the 'enemy', extreme close-mindedness, underhanded debating tactics, justifications, and all manner of name-calling and character assassination" - William J. Beaty

"Cut through the ridicule and search for factual information in most of the skeptical commentary and one is usually left with nothing. This is not surprising. After all, how can one rationally object to a call for scientific examination of evidence?" Bernhard Haisch, Ph.D.,

"Be Skeptical of the Skeptics" "Skeptics, who flatly deny the existence of any unexplained phenomenon in the name of 'rationalism,' are among the primary contributors to the rejection of science by the public. People are not stupid and they know very well when they have seen something out of the ordinary. When a so-called expert tells them the object must have been the moon or a mirage, he is really teaching the public that science is impotent or unwilling to pursue the study of the unknown." - Dr. Jacques Vallee, astrophysicist, computer scientist and world renowned researcher. He worked closely with Dr. J. Allen Hynek. Commenting on the need for science "to search beyond the superficial appearances of reality"

"Healthy scepticism is good, but this kind of scepticism is ridiculous. Non-awareness is NOT synonymous with non-existence, and disbelief in something does not in any way detract from its reality. No one can create a fact by making a statement, and no one can get rid of a fact by denying it." - Wilbert Smith

"To state there is no evidence suggestive of intelligent extraterrestrial life simply belies the facts. Decades in duration and global in nature, there are too many hard sensor data-points and millions of eyewitnesses to ignore. It is only through ignorance or pomposity that one can say no evidence exists" - John B. Alexander

"The progress of science depends on a finely tuned balance between open-mindedness and skepticism. Be too open minded, and you'll accept wrong claims. Be too skeptical, and you'll reject genuine new discoveries. Proper skepticism must be careful not to throw the baby out with the bathwater. Unfortunately, much of what comes out of the "skeptical" community these days is not proper skepticism, but all-out, fundamentalist disbelief. Such skepticism can be called pseudo-skepticism, pathological skepticism or bogus skepticism." - Rochus Boerner

This cylindrical-appearing UFO was photographed over New York City on March 20, 1950. The photographer's name was deleted from Project Blue Book's files -- as were most names when the material was finally declassified and released. Upon investigating the report, Project Grudge officially labeled it: "the moon"! Some ufologists have speculated that tubular objects of this sort may be "mother ships," purportedly capable of taking on and discharging smaller "craft" in stacks, poker-chip fashion.

The National Oceanic and Atmospheric (NOAA) has several Geosynchronous Orbiting Satellites in orbit watching the Earths weather and environment. On November 21, 1999 at 14:45 hours, one of the satellites caught an amazing photo of a UFO at an estimated hundred miles above the Earth off the state of Washington.

One of the satellites is designed to detect water vapour or clouds from space and when its camera was zoomed in, it was apparent that the craft was giving off vapour. The possibility of a computer error causing the image was completely ruled out . The UFO was present for several minutes and was a structure which radiated heat in the infrared spectrum. It was obviously very large. Similar photos were taken on June 8 , 1995 over South America.

September 03, 1993 - Earth Orbit - METEOSAT photo

In 1991, the New York State Physics teacher Philip J. Imbrogno discovered that meteorological satellites sometimes send strange images down to Earth. He published several of these images, received from the geosynchronous GOES-Satellites of NOAA, which show egg-shaped objects in the Earth Orbit. Critics immediately came up with an explanation: According to them, they were mere "moonshadows".

This explanation was maybe acceptable when the first images showed no details. But after Chilean researchers published photos of a structured saturn-shaped craft of 400-600 feet in diameter, it immediately collapsed.

Meanwhile, Italian researcher Adriano Forgione published this image, received by the Italian radio amateur Vittorio Orlando on September 3, 1993 at 6.30 p.m. from the METEOSAT weather satellite, stationed in an altitude of 95.000 feet. In the original as well as in the enlargement, a dome and a surrounding ring are clearly visible. Another moonshadow? Or indeed a "structured craft"?

On March 10, 1977, at between 3:30 and 4 p.m., Ricky Brandenburg, 13 had just arrived home from school in Indianapolis. Indiana, when he saw an object coming out of the north at low altitude. He at first thought it was an airplane, but it made no sound and had an odd shape. His mother and a neighbor were in the yard and he called to them, "Look, a UFO." They paid no attention, so he ran into the house and got his Instamatic camera which was loaded with color film in preparation for a projected visit to the Museum of Science and Industry. He ran into the yard and began snapping pictures. The object made a 360° circle above the neighborhood, during which time Ricky snapped nine photos. Of the nine, only three clearly showed the object; they were numbers six, seven and eight.

After the object completed its sweep of the area it went back into the north and "just disappeared in the clouds." Ricky then went inside and told his parents. His father. Morce Brandenburg, told Field Investigator Fritz Klemm that he at first didn't believe Ricky but when the photos were developed he was convinced Ricky has really seen and photographed a UFO.

Photo number six shows a dark disc-shaped object with what appears to be a transparent dome against a blue sky and scattered clouds. Number seven shows the object further away than number six, but under a powerful magnifying glass, a slightly orangeish tint is visible on the lower part of the object. On number eight, which is considered to be clearest of the three, the area just above the rim of the disc shows an orangish hue.

Weather conditions were the following: Wind out of the SSW at 13 knots, temperature 65 degrees, barometric pressure 29.145 and steady. As noted earlier, there were scattered clouds. Mr. Klemm was not able to accurately check the air traffic because he could not pinpoint the exact time of the sighting.

These photos have been examined by Dr. B. Roy Frieden, APRO's Consultant in Optics,' Dr. Daniel Harris, APRO Consultant in astronomy, as well as other members of the headquarters staff and are considered to be genuine.

The Hannah McRoberts photograph, Canada, 1981

On October 8, 1981 at abour 11:00 A.M., Hannah Mc Roberts is with her husband and their daughter on a service area close to Kelsey Bay, on the East coast of the Vancouver Island. During their pause they notice a cloud which passes on the top of a mountainous peak and makes the impression of an erupting volcano in eruption spitting a huge vaporblast. They find the scene rather amusing and worth a picture.

Several days afterwards, when the photographa are developed, they notice on one of the photograph that there is a discoidal object in the sky. Their surprise is big, as they do not remember noticing anything in the sky at the time when they shot the photograph.

They contact David Dodge, director of the of Vancouver planetarium. He examines the picture and remains disturbed by this singular photograph. He contacts a ufologist, David Powell, who analyzes the pictures and cannot find any evidence of tampering.

Richard F. Haines, a retired NASA scientist who became a famous ufologist, gets interested in the Vancouver case. He carries out a thorough analysis of the negative and cannot discover any tampering either. His analysis is inserted in the scientific report of the Sturrock Panel.

With regard to the lady who took the photograph of this UFO, Mr. W. K. Allan says: "What is of great importance to me is the fact that Hannah McRoberts is the niece of one of Canada's leading nuclear engineers, a man in charge of a multi-billion dollar electrical generating complex, whom I have known continuously since his attendance in my class at Western Canada High School in Calgary, Alberta." - Mr. W. K. Allan

(The place where Mrs. McRoberts says she took her photograph lies incidentally, some 450 kms or so to the north-west of Mount Rainier in the US State of Washington, where, as readers will recall, Kenneth Arnold claimed on June 24, 1947 to have seen his famous flight of nine saucers moving in formation at 1,200 mph and at an altitude of 10,000 ft over the Cascade Range.)

BUDAPEST, Hungary - A military pilot recorded a spectacular video of a silver disk object on September 29, 2001. The craft was flying to his left side and then moved very fast past him in the clouds as can be seen in the video.

"I was on a flight over Budapest, Hungary," said the pilot, who has requested that his name be withheld until the official inquiry by the Hungarian Ministry of Defence is complete.

"To my left I saw a bright metal aircraft that was the shape of a perfect disk. I was careful to film the object, not to try and chase it since it I could not match its speed. As I was flying a reconnaissance aircraft, I got the idea to film it and used our equipment."

Officials at the Ministry of Defence would not answer questions about the video when asked and warned that officially they have no comment. Despite the denial, when informed of the pilot's name, they did acknowledge that the he was a real air force pilot and that it was true that he flew photo reconnaissance airplanes.

The pilot considers the video he made to be his property and not the Hungarian governments as he was flying the plane while not on duty and was transporting it as a favor to save the government money. He has now hired an attorney and wants the video to be released to the public. He hopes the release of a few frames will make this happen.

In the early hours of March 23, 1981 Carlos Diaz, a young photographer from Mexico City, drove into the Ajusco National Forest in the "zona vulcanica" south of the capital. A magazine had commissioned him to take pictures of a sunrise in the mountains, and for this he has chosen a well-known vantage point. He parked his car, waited for the sun to dawn. Suddenly he saw an orange light shining up from the slope in front of him. First he thought it was a fire, but then he recognized a yellow-orange dome. It was a UFO! Immediately he grabbed his camera, shot a first photo, when the disc was just facing him. In this moment, the engine of his car went off. Diaz shot his second picture before he jumped out of the car, just to see and photograph how the disc was shooting off with high speed.

When he got the photos back from the lab the same afternoon, Diaz knew that he did not dream. This experience never let him off. As often as possible he returned to the Ajusco National Park. But only two and a half month later, on a rainy day, he saw the orange glow again, this time coming from the top of a hill. He parked his car, climbed up the muddy volcanic rocks, when he eventually saw the object hovering in front of him. Deeply moved by what he saw, he suddenly felt someone touching his shoulder. In the same moment he fainted. When he recovered, the rain had stopped and the object had disappeared. Completely bewildered, he climbed down the hill, back to his car…

In the following month, Diaz started to remember step by step what had happened to him during that "missing time". More than that, a friendly contact developed between him and the pilots of these mysterious "Ships of Light". Carlos decided to move into the valley of Tepoztlan, 40 miles south of Mexico City, where these objects were seen since man can remember. He was able to take several more spectacular photos. And he had further encounters which taught him why these beings come to this planet and how worried they are about all life, all living beings on Earth.

Ten years later, the sun was darkened over Mexico. During the eclipse of July 11, 1991 thousands of witnesses saw strange craft in the skies. The prominent TV anchorman Jaime Maussan investigated the sightings, commissioned a scientific analysis of UFO footage. Carlos felt that the moment has come to go public with his experience. He contacted Maussan who was deeply impressed by the quality of his photos. More than that, he tried an experiment. He gave Carlos, who could not afford one, a video camera. He was not disappointed. Only three days later, Carlos presented him the first film. Three more followed within the next five month. They all show the same "Ship of Light" which was also on his photos, in breathtaking maneuvers over the valley of Tepoztlan. One time it came so low that it filled the whole frame of the camera.

Thousands of eyewitnesses, radar observations, photos and films which stunned the experts and a contactee with a high degree of personal integrity – the Carlos Diaz experience can indeed be called one of the most important UFO contact cases in the history of the phenomenon. For this reason, the researchers investigated it as careful as possible – and waited seven years, until every aspect was put under scrutiny, before they published it. Never before so many international experts were consulted in the investigation of a UFO contact case. All researchers who met him were impressed by the honesty and sincerity of Carlos Diaz, an impression shared by his neighbours, his family, the mayor of Tepoztlan. Nobody in Tepoztlan ever questioned his experience since the majority have seen these objects, too.

McMinnville, Oregon - May 11, 1950: Two of the most notorious UFO photos of all time were taken on a farm near Mcminnville by a farmer named Paul A. Trent. Beyond many such cases, these two photos have withstood the test of time--through generations of researchers. It could be said that this case specified the boiling point for the heated ongoing debate over what qualifies as physical evidence--at least when it comes to the subject of UFOs.

Mrs. Trent was outside getting finished feeding her rabbits, when she noticed the large, disc-shaped object approaching from the northeast. She called out to Mr. Trent who joined her to look at the mystery device. After a few moments, he went back in the house to get his camera. He got back out and picked a spot to stand and took the first picture, then wound the film for the next picture. (That was typically a time consuming process with a 1950 box camera.) Several minutes later, he took the other.

In the meantime, Mrs. Trent called out to her in-laws on their porch, about 400 feet away. They didn't hear her, so she ran into the house to call them on the telephone. Mrs. Trent's mother-in-law didn't get to see it because it disappeared by the time she was off of the phone, but Mrs. Trent's father-in-law did catch a glimpse of it just before it disappeared in the west.

Mr. Trent waited to finish the roll of film before he got the pictures developed. They were displayed nearly a month later in a local bank. (The Trents' banker worked there.) A reporter named Powell, who worked for the McMinnville Telephone Register, saw the photos and convinced the Trents to let him publish their story and photographs. However, it did take a bit of coaxing because the Trent's feared they might get in some kind of trouble with the government.

The photographs and story wound up in the June 26, 1950 issue of Life, who borrowed the negatives from Powell. The Trents didn't get the negatives back for another 17 years. They were requested for examination by the Condon investigation in the late 1960's, and after that analysis was done, they were finally sent back to Mr. Trent.

The first people to examine the negatives found no signs of manipulation of the negative and no visible means of support for the UFO pictured, and so it has remained, for over half a century. No scientific study of this case has ever revealed anything that contradicts the witnesses or their fortunate photos.

Newsmen Ed Kessel and Joao Martins of O'Cruzeiro Magazine, covering a groundbreaking ceremony near Copacabana, saw a strange aircraft approaching. Cameraman Ed Kessel snapped five black and white photographs as the UFO came directly over them, circled Pedra de Gavea Rock, and then flew back out to sea. The developed prints showed a clearly outlined and sharply detailed solid-looking disc shaped object estimated to be at least 50m in diameter and 5m high.

Brazilian Air Force investigators tracked down at least 40 people who were in the vicinity that day and were witnesses to the object in question. All of their stories matched descriptions given by the two newsmen who produced the photographs. During the course of their analysis of the case and photos, Brazilian military investigators tried to reproduce the photos to see if they could have been faked. (They were unsuccessful in all attempts.) This led to a few people who were later interviewed by investigators for Project Blue Book to state they had seen men in the area making fake UFO photos. This in turn led Blue Book staff to write the case off as a hoax.

The in-depth photo analysis by Aerial Phenomenon Research Organization (APRO) started off with the hoax explanation due to a shadow on the trunk of a lone palm tree in one of the photos not matching the shadow angles on the UFO. Field investigators in Brazil informed APRO that a couple of dead branches shaded the tree's trunk in such a way to create an optical illusion that the shadow angles did not match the UFO.

In the end, Brazilian investigators had searched every angle of the story to find evidence of a hoax, but never found it. The two newsmen were considered very reliable and there was no apparent motive for 40 or more additional and unrelated witnesses to perpetuate the story if it was not actually true.

Trindade, a small rocky island in the middle of the South Atlantic Ocean 600 miles off the coast of Bahia, Brazil, was the site of one of the most impressive photographic cases in UFO history.

In October 1957 the Brazilian Navy set up a small scientific base on the unoccupied island, where oceanographic and meteorological research would be conducted in connection with the International Geophysical Year. Starting early the next month, instrument-bearing weather balloons were launched daily. They were designed to explode in the upper atmosphere, releasing the instrument packages which would parachute to earth to be retrieved by the researchers. By the end of the month base personnel were reporting silvery UFOs which seemed to be monitoring the balloons’ movements.

On January 1,1958, at 7:50 A.M., the passage of a bright point of light, like a mirror reflecting sunlight, was observed by the entire garrison. The next evening a round object with an orange glow circled the Navy tow ship Triunfo traveling off the Bahian coast 400 miles from Trindade. As the crew watched, the UFO executed sudden right-angle turns and at other times hovered near the ship. The sighting lasted for 10 minutes.

The most fantastic event occurred on the sixth. The base’s chief officer, Cmdr. Carlos A. Bacellar, had just overseen the launching of a weather balloon into a morning sky clear of everything but a single large cumulus cloud at 14,000 feet. Inside the radio cabin Bacellar listened to the signals the balloon emitted as it ascended. Suddenly those signals inexplicably diminished, then went dead.

When Bacellar went outside to investigate, he saw nothing out of the ordinary, at least at first. The balloon was ascending normally—until it came directly below the cloud, at which point it seemed to be sucked abruptly upward. For the next 10 minutes it remained out of sight and inside the cloud. Finally, when it reappeared, it was above the cloud and devoid of the instrument package.

Soon a silvery object emerged from behind the cloud. As it moved slowly from the southwest to the east, a technician gazing through a theodolite spotted it and alerted the commander, who viewed it briefly through binoculars, then through a sextant. Crescent-shaped and bright white in color, the object reversed course at one point and remained in sight for some time before it entered a cloud bank (Fontes, 1960).

Rex Heflin, an Orange County highway inspector, was at work in a county vehicle at 12:37 P.M when he saw a hat-shaped (disc with dome) object hovering above the road. He grabbed his Polaroid camera normally used to record highway obstructions or other problems and took three photographs of the metallic-appearing object and a fourth of a black "smoke ring" left behind by the object after it departed at high speed. He reported seeing a rotating band of light on the underside of the object (like the sweep of a radar beam).

Heflin twice tried to radio his base, during the sighting, but the radio would not work. (It functioned normally after the object departed.) One of the photographs was published by the Santa Ana Register on September 20, 1965; then the story was picked up by the national newswire services.

The Los Angeles Subcommittee of NICAP, headed by Idabel Epperson, conducted a thorough investigation of the case, including a detailed character and background check, on-site investigation and measurements (by engineer John Gray), and photoanalysis. Both Heflin and the newspaper cooperated fully in the investigation.

Computer enhancement and photoanalysis was conducted by Robert Nathan at the Jet Propulsion Laboratory, working with first-generation prints and copy negatives made by the newspaper. Among other things, the analysis established photographic evidence to confirm the "light beam" on the underside of the object. The Air Force issued a statement declaring the photographs a hoax, which was strongly disputed by NICAP. Nathan specifically ruled out a model suspended by a string as the explanation.

Unknown parties later attempted to tamper with the evidence and manipulate information. The copy negatives were obtained from Heflin under false pretenses, by someone pretending to be from the North American Air Defense Command. Years later, Bill Spaulding of Ground Saucer Watch using computer enhancement techniques reported finding a linelike marking above the object, suggestive of a supporting string, implying that the UFO was hoaxed by using a small model. However, the alleged "line" clearly was either an artifact created by multigenerational copying of the photographs or a deliberately introduced marking to discredit Heflin. No such line was found in the originals by Nathan, the newspaper, or NICAP analysts.
