Before taking this series, they turned the flag so that it was face on to the 16-mm DAC mounted on the MET ( This is the orientation seen in the tourist pictures, AS14-66-9231, 9232, and 9233).

After they finished taking these three tourist pictures, they turned the flag so it was face on to the TV camera (Photo AS14-66-9324). See a discussion following 131:09:18.
Flag Position 3
During the current depressurization, at about 131:10:26, the flag suddenly moves out of the TV field-of-view and, as can be seen after 135:02:45 when Al gets back to the LM at the end of the traverse and re-aims the TV, it ends up pointing at the TV on an azimuth of about 045. A frame from Ed's Station H pan, AS14-68-9486 provides additional evidence.

Flag Position 4
Finally, we note that AS14-66-9338, a picture taken out Ed's window after the PLSS jettison, shows that the flag has moved again, undoubtedly as a result of the pre-jettison depressurization; ending up pointing at an azimuth of about 335
As for the timing of the first flag motion - which is clearly a result of the EVA-2 depressurization - we note that the dump valve in the forward hatch was first opened at about 131:07:09. The interval from the second valve opening to the corresponding arrival at the CCIG - 190 meters from the LM - is about 30 seconds. The time at which the flag moves, 131:10:26. What seems to be required to explain the movement of the flag is that Shepard 'cracked' the hatch open - but without fully opening it - about 30 seconds before the third CCIG peak about 131:10:01; and that the resultant oxygen flow was far less directional than the flow out the valve, arrived at the flag before arriving at the CCIG, and imparted sufficient force on the flag to move it. The limited availability of Apollo 14 data does not allow us to be very precise; and what is required to sort out what actually happened is a detailed numerical simulation and/or carefully designed laboratory demonstration Thanks to Journal Contributors Ian Regan, Harald Kucharek, Ken Glover and to members of the Bad Astronomy bulletin board for raising the issue of the orientation of the Apollo 14 flag and for helpful input...
Hmmm... what did Bad Astronomy, and they do mean bad, say about the lack of crater on the moon?
Now here comes a little bit of math: the engine nozzle was about 54 inches across (from the Encyclopaedia Astronautica), which means it had an area of 2300 square inches. That in turn means that the thrust generated a pressure of only about 1.5 pounds per square inch! That's not a lot of pressure. Moreover, in a vacuum, the exhaust from a rocket spreads out very rapidly. On Earth, the air in our atmosphere constrains the thrust of a rocket into a narrow column, which is why you get long flames and columns of smoke from the back of a rocket. In a vacuum, no air means the exhaust spreads out even more, lowering the pressure. That's why there's no blast crater! Three thousand pounds of thrust sounds like a lot, but it was so spread out it was actually rather gentle.

"In a vacuum, no air means the exhaust spreads out even more, lowering the pressure."
So how much pressure did it take to spin that Flag around? Why did it not continue to spin or flap? And why didnt it just fall over? It simply doenst make sense.
Check out the lift off.
What did they do, superglue the flag pole into the ground?
And look at the first picture.
That flag looks like its flat on the ground!
I mean what the hell
Does US propaganda have no shame?

What is your specific evidence that contradicts this scientific knowledge about radiation and the Apollo missions? Could you show me the investigations and calculations you have done that proves all of the other scientists wrong?
...(By the way, Dr. Van Allen himself said that the astronauts were not on the van Allen belts long enough to be subjected to very dangerous doses of radiation. Are you now doubting Dr. Van Allen himself?

Oh sorry i thought you were some sort of expert or astronaut....my mistake
I dont need to read a load of threads to know it was faked, these are just a few of my questions that cannot be explained.
