I just wanted to place this link here for the next time someone tries to make a claim based on the "expertise" of a professional pilot thinking they know everything they see.
Pilot sends plane into dive after mistaking Venus for oncoming plane
And it's not just a simple matter of being drowsy or ill and mis-identifying it for the airplane that was in the vicinity.
The first officer was told by the captain it's not the plane. Each plane even flashed thier lights for confirmation. The first officer still took his own action.
