I read some of the things that the astronauts are to have said, and according to what you said:

A report by an astronaut of an object he felt to be another spacecraft, particularly one of extremely unusual design, would have been taken seriously. Several reports by different astronauts of that nature would have provoked a formal investigation. If reports of that caliber continued to accumulate, there would be a crash program to find out what was going on

Should there not be a crash program to find out what is going on?

On coast-to-coast television, Cooper recently made a blockbuster statement that had the telephone lines tied up the next day, as viewers telephoned the stations which carried the syndicated Merv Griffin Show, anxious to find out if their ears had been playing tricks on them the night before.

Toward the end of the talk-show host's interview with the former Astronaut, Merv broke into a secretive tone of voice right on the air, and aimed a hundred-thousand-dollar question at his guest: 'There is a story going around, Gordon, that a spaceship did land in middle America and there were occupants, and members of our government were able to keep one of the occupants alive for a period of time. They've seen the metal of the aircraft and they know what the people look like - is that a credible story?'

For all intents and purposes Cooper should have laughed for assuredly such a speculative story belongs in the category of science fiction or space fantasy. But Gordon Cooper kept a straight face when he replied: 'I think it's fairly credible. I would like to see the time when all qualified people could really work together to properly investigate these stories and either refute or prove them.'

The bombshell had been dropped. Cooper went on to say that from the various reports of UFO contacts and abductions he had been privy to, he was convinced that the occupants of this crashed UFO were 'probably not that different from what we are,' - that they are almost totally humanoid (i.e., have two arms, two legs, a torso and readily identifiable facial features) in appearance.

Taken aback by what Cooper had said over the national airwaves, Lee Spiegel telephoned Cooper's office the following morning and managed to get past his private secretary, though others in the media were getting the cold shoulder.

'Cooper admitted to me that he could have revealed more on the air, but he decided not to play his entire hand because he felt certain that some 'official eyebrows were going to get raised'.'"

According to a former NASA employee Otto Binder, unnamed radio hams with their own VHF receiving facilities that bypassed NASA's broadcasting outlets picked up the following exchange:

NASA: Whats there?
Mission Control calling Apollo 11...

Apollo11: These "Babies" are huge, Sir! Enormous!
OH MY GOD! You wouldn't believe it!
I'm telling you there are other spacecraft out there,
Lined up on the far side of the crater edge!
They're on the Moon watching us!
