Not a planefag per se, but am a acft mechanic. Try & get the tail number if u can, for the U.S it'll be the 'N' number. The letter correlates to the country & every country has it's own letter/combo of letters. By law all planes tail numbers are registered with the FAA & supposed to be publically available. That can give you info on at least who/where the plane is registered. If they are used for nefarious purposes then they use shell companies. But it's at least a place to start.
