>Chasing down misidentified flying objects and hoaxes will not. The idea that numerous spaceships, each with more potential kinetic energy than mankind has created in its entire history, are just flying around our atmosphere without leaving massive and easily recordable emissions is ludicrous.

Identifying, understanding and explaining/eliminating exceptions is how science progresses. I know it causes discomfort to see something that defies expectations right in front of you. That does not mean we do not examine it. We should.
