I remember a French documentary from a while ago and a helicopter pilot said that he witnessed something similar while he was flying. A large cylinder craft flew past him rapidly and was relatively close to the helicopter to the point that this would have affected it (air displacement?), but nope. It was as if the "UFO" flew inside its own sort of bubble, isolated from the surrounding environment. Flew right past the helicopter as if it was nothing. That's what was the most shocking.
