Ah, Roswell again – it must be the summer silly season.
1. Why not? How can we definitively say not?
2. Original press release
3. Water appears to have been found elsewhere
4. Witness testimony and on the spot, esp. Haut
5. Why couldn’t they crash, just as any craft can?
1. Start of Cold War, wanting to frighten the Russkies and Chinese
2. This CIA man won’t say what it was but wants to sell his book
3. Water has not been found elsewhere
4. Friend once told me about UFOs being seen but this one was an MOD project
5. Disc not the most effective shape for the craft
Not bothering with
1. They couldn’t carry that much fuel
2. Superior technologies don’t crash
3. Any other “they wouldn’ts” or “they couldn’ts”
4. It’s simply not possible
