Two quoted letters:
‘Have We Visitors from Space?’ (LIFE, April 7) is the most comprehensive reports I have read on the subject. I was very closely associated with Projects ‘Twinkle’ and ‘Grudge’ at Alamogordo, N. Mex. where I was chief of the technical photographic facility at Holloman Air Force Base. I have seen several of these objects myself, and they are everything you say they are as to shape, size and speed.

I first learned about the green fireballs from Marine Corps night fighter pilots while I was an aviation intelligence officer in Korea.
Pilots often reported seeing strange bright green objects in the skies, unlike anything they had ever seen before, and moving too fast and regularly to be exlained or identified or analyzed by the pilots themselves or the intelligence officers.
