More videos like this, even better if powerful telescope used.
This experiment needs to be repeated!
5. From an article published in both Fortschritt für alle (Progress for everyone) ; Schlossweg 2 D-90537 Feucht Germany and the magazine Geokosmos, issue 11/12, December 1963. (Source Rolf Keppler’s website). The optical research division of the US Army Signal Corps developed a camera which was made to see objects 30 miles away. The Empire State Building and the outlines of Manhattan were photographed at 26 miles distance, including all the preceding ground and other objects, all from the Atlantic Highlands about 3 feet 3 inches above the ground! At this height the horizon for a convex Earth is calculated as 1.22 multiplied by the square root of 3.25 feet (height) which is 2.2 miles. This is what the limit of the US military camera should be for a convex Earth… but wasn’t. Instead it saw nearly 12 times further than that. Twelve times! And that’s not including the 30-mile horizon it was designed for, which would make it see 14 times more than it should.
Houston, we have a problem.
The reason this camera saw the horizon at 26 miles distance at a ground height of 39 inches is because of refraction… obviously.
Taking 2.2 away from the 26 miles seen by the military camera gives 23.8 miles. To calculate how far the object should be below the ground for a convex Earth take the square of 23.8 (distance) multiplied by 8 inches (difference in ground altitude of the first mile) which is 377 feet. In a convex Earth, Manhattan should have been invisible with only the top two thirds of the Empire State building above the horizon (1,250 ft height)… but not only were they fully photographed, so was everything else up in front of them… and how. The photograph shows 3 horizons; the first being the lighthouse at Sandy Hook at 4 miles distance, the second was Coney Island at 13 miles away, with the last being Manhattan at 26 miles. The furthest horizon was at the top of the photo, not the bottom; and to really throw the cat amongst the pigeons, the camera was pointing up. Pointing up! How else can this be explained unless the Earth is concave?
Sandy Hook, followed by a 9-mile wide bay, then Coney Island, followed by another bay, then finally Manhattan at the top of the photograph are all shown in series.
The camera was pointing upwards showing it was not at an elevated position and that all objects photographed must have been situated higher than the camera.
Below are the full details of the article:
The optical research division of the US-Army Signal Corps has just issued a new camera, which is specially suited to take photos at a distance of 50 km (30 mi.). The objective has a focal length of 254 cm (100 in.), it is 1 m long and has a diameter of 24.13 cm (9.5 in.), it has been corrected for using infra-red film.
Using this objective it is quite easy to analyze the terrain up to a distance of 10 to 20 km (6-12 mi.) and distinguish weapons, fortifications and transports. The disadvantage of such a teleobjective is the complete elimination of perspective.
The photo reproduced, shows the Empire State Building and the outlines of Manhattan at a distance of 41.8 km (26 mi.) At the bottom of the Empire State Building a large hotel is visible on Coney Island, however, it is only 20.9 km (13 mi.) distant from the camera. One could never tell from this photo that between these two buildings there is a distance of 21 km. The lighthouse of Sandy Hook, in the foreground of the photo is only 6.4 km (4 mi.) distant from the camera.
The new teleobjective is coupled to a 13 x 18 cm camera which can either use film cassettes or rolls of film. Each roll of film contains 30 exposures, however, a built-in cutter can be used to cut off exposed parts of the film.
They can be lifted out with the take-up spool. The shortest distance to still produce a sharp photo with this teleobjective is 500 m (1 600 ft.) In this case the width of the photo covers 31 m (100 ft.) At a distance of 20 km (12 mi.), which is the last point before infinity, the section of the photo covers about 1 000 m (3300 ft.)
The telescope, which is used to focus the camera has a magnification of 10 and shows the exact frame of the photo to be taken. When adjusting for the proper distance, the heavy objective, which is firmly mounted on the tripod, is not moved, but instead one only moves the camera.
The device weighs about 64 kg (140 lb.) and must be operated by two men. The whole camera is carried, with two handles each on front and back, like a stretcher. The device can be set up, aimed and adjusted, all within 5 minutes.
Interesting that yet again it is the US military that not only has sulfur lamps installed, but also possesses extreme long distance cameras which show the Earth’s concavity. This is no surprise as knowing the correct Earth model would be paramount to an organization like the military. It makes you wonder what other toys and knowledge they have at their disposal.
Optics has shown that the “hull vanishing before the sails” effect is not in any way evidence for a convex (or concave) Earth. The US military camera pointing up and showing “3 horizons” with the furthest one situated at the top of the picture cannot be explained by any convex or flat Earth model, only a concave one; and proves that the horizon we see with the naked eye is caused by optics. The only question is the reliability of this information and that we have no other examples with which to compare; so for that reason alone, this evidence is not a slam dunk. Does the US military camera show that the Earth is concave? Very likely (95%).
