If you do want to make it sinister, these planes are used to test all kinds of military equipment and weather equipment. They put the stuff inside, have complete labs, and don't put ID on the planes. Then they fly them at all kinds of speeds and altitudes to test the equipment. I can't imagine that this plane in BELIZE! Is being used for that! The biggie, a white, no lable 747, named Queenie, out of Pax would regularly impress us for loud, low level, and strange flying.
