....But, just falling from about 200,000 feet is NOT going to accelerate an object to such speeds.....ever hear of "terminal velocity"???
Terminal velocity is not a set figure Weed, it varies due to air resistance..
Not much air at 200,000'..
At 400,000 feet, a pre-entry phase begins in which the orbiter is maneuvered to zero degrees roll and yaw (wings level) and a predetermined angle of attack for entry. The flight control system issues the commands to the roll, yaw and pitch RCS jets for rate damping in attitude hold for entry into the Earth's atmosphere until 0.176 g is sensed, which corresponds to a dynamic pressure of 10 pounds per square foot, approximately the point at which the aerosurfaces become active. When the orbiter is in atmospheric flight, it is flown by varying the forces it generates while moving through the atmosphere, like any other aerodynamic vehicle.
The orbiter makes a series of S-shaped, banking turns to slow its descent speed as it begins its final approach to the runway. The commander picks up a radio beacon from the runway (Tactical Air Navigation System) when the orbiter is about 140 miles (225 km) away from the landing site and 150,000 feet....
During launch, the S-IC fired its engines for 168 seconds (ignition occurred about 7 seconds before liftoff) and at engine cutoff, the vehicle was at an altitude of about 42 miles (68 km), was downrange about 58 miles (93 km), and was moving about 7,850 ft/sec (2,390 m/sec, or approximately 5,352 mph).
Nit pick much?

And when would be the most opportune time for the US to reveal this?
Half time at the Super Bowl.??
Though really, I haven't been convinced of the hoax yet..
NASA could easily launch a lunar mission, like an ICBM, with 5 rovers to the moon, each remotely controlled by NASA, which could investigate each of the Apollo landing sites, for the posterity of all mankind. "One great leap for all mankind." It would be such a great, cheap stunt. I can't believe they haven't done it yet.
About 100 miles (161 km) above the Earth is a region of darkness and complete silence. This is called the Black Sky region. The stars appear as brilliant points of light and the area between them is jet black because there is not enough air to scatter or reflect the light rays.
The Kármán line lies at an altitude of 100 kilometres (62 mi) above the Earth's sea level, and is commonly used to define the boundary between the Earth's atmosphere and outer space.[2] This definition is accepted by the Fédération Aéronautique Internationale (FAI), which is an international standard setting and record-keeping body for aeronautics and astronautics.
The astronauts reported that the Far Ultraviolet Camera was extremely easy to unload and transport; however, it did have to be moved twice after being set up to keep it in the shadow of the LM. The camera was in operation for approximately 51 hours and was repointed 11 times during the mission. The film was retrieved at the end of the third EVA.
Long-exposure photos were taken with a special far-ultraviolet camera by Apollo 16 on April 21, 1972 from the surface of the Moon. Some of these photos show the Earth with stars from the Capricornus and Aquarius constellations in the background. The joint Belgian/British/Dutch satellite TD-1 later scanned the sky for stars that are bright in UV light. The TD-1 data obtained with the shortest passband is a close match for the Apollo 16 photographs.
NASA (National Aeronautics and Space Administration) selected Nikon products as payload cameras for the spaceships Apollo 15 to 17 in the Apollo Program which had been launched in 1961 aiming at manned lunar landing, and in January 1971 we entered into a contract with NASA to supply our cameras.
35-millimeter Nikon Camera
The 35-millimeter Nikon camera was mounted in the righthand rendezvous window and periodically made time exposures during the dark portion of the lunar orbit. The purpose of the experiment was to determine whether, and to what extent, reflection from dust particles at the Moulton point contributes to the gegenschein. The gegenschein region was not acquired but, instead, the camera photographed another part of the Milky Way as a result of a translation error in coordinates from the ground.

Something else to add to the list of subjects that arn't your forte along with physics, space flight, science in general and common sense - Photography.
What exactly is 'Normal film exposure' Foos? How many milliseconds or seconds was it exposed for? And more importantly - SOURCE PLEASE.
Since we have been debating the stars issue.

3 days this astronaut was sitting going around and around the moon and he never thought about taking shots of the cosmos? Not for his family, not for himself, not for science? Not even planets? No? Not interested? Just the moon and Earth?
On a side note: the photos from this "camera" could have been taken from Earth orbit. So what was the point of bringing it, and how do we know these photos do not come from satellites?
Ridicules
and
Unbelievable.
And your forte is not spelling or photography.
You don't know what they mean by normal exposure?
Well I do.

Ahhh too bad…
Ok, what about Apollo 16?

You should read all the posts, not just skip through them.

At times of peaks in solar activity, there are more geomagnetic storms and this increases the auroral activity viewed on Earth and by astronauts from orbit. Photographing them requires careful technique with long exposures and fast film (in this case ASA 1600).
Such film can only be used on short-duration Shuttle flights and not from the Space Station because it is sensitive to radiation damage in orbit over time.
