"I was testing a P-51 fighter in Minneapolis when I spotted this
object. I was at about 10,000 feet on a nice, bright, sunny afternoon. I
thought the object was a kite, then I realized that no kite is gonna fly
that high. As I got closer it looked like a weather balloon, gray and about
three feet in diameter. But as soon as I got behind the darn thing it didn't
look like a balloon anymore. It looked like a saucer, a disk. About the same
time, I realized that it was suddenly going away from me -- and there I was,
running at about 300 miles per hour. I tracked it for a little way, and then
all of a sudden the damn thing just took off. It pulled about a 45 degree
climbing turn and accelerated and just flat disappeared."
