Retired Cmdr. David Fravor spent 18 years as a Navy pilot, but nothing prepared him for what he claims to have witnessed during a routing mission on Nov. 14, 2004.
"I can tell you, I think it was not from this world," Fravor told ABC News. "I'm not crazy, haven't been drinking. It was — after 18 years of flying, I've seen pretty much about everything that I can see in that realm, and this was nothing close."
Fravor claims that his encounter off the California coast was with what appeared to be a 40-foot-long wingless object that flew at incredible speeds in an erratic pattern.
"I have never seen anything in my life, in my history of flying that has the performance, the acceleration — keep in mind this thing had no wings," Fravor said.
