Whatever the case, the US Army Aircorps, after first announcing they had found a saucer, then recanted and said it was nothing more than a weather balloon. The confirmed this later, in 1995, saying it was Balloon 4 from the top secret Project Mogul flight.
So was it a saucer, or a balloon?
Well in order to taunt everyone, NASA, decided to design a saucer shaped craft, attach it to a helium balloon and send it up into space . . . they say to test a vehicle for possible landing on Mars.
The test ended when one of the devices parachutes failed to open and the saucer . . . you guessed it . . . crashed.
Of course it did so in the Pacific, how awesome would it have been, if it had crashed in New Mexico!
