This is a Pandora or Pandorus sphinx moth, Eumorpha pandorus. It seems appropriate that it was hanging out at the airport as it resembles a stealth bomber that is painted in jungle camo, like Mother Nature had been watching too many Rambo movies that day. They fly predominately at dusk on green to brown wings that can span 4.5 inches. Their wing shape looks a lot like the somewhat smaller hog sphinx moth.
