N987SA is a familiar ID
Couple of months ago I was playing with a database of flight plans which covered a timescale up to around 2006 and N987SA appeared - complete with it's flights to and from Schenectady County (USA), Tashkent, Bucharest etc - all places known to have upmarket vacation resorts.
Unfortunately the data never included the flight plans for N987SA in 2007 - ie the time it "crashed" in Mexico. But... one weirdo aspect of this flight was that the aircraft was heading northbound and being intercepted by Mexican aircraft/copters. Ya got to wonder where it was planned that this aircraft would land with 3 tons of baking powder - it's not exactly an "unnoticeable" aircraft and would obviously be subject to inspection wherever it landed - unless their was extensive "cooperation".
Another aircraft tail marking with a colorful history is N168D (which may be known as multiple other numbers at various times). At one period there were two N168D's flying (duh??) and one was photographed in.. think Europe, while at the same time, the other was being impounded in South America as a suspect aircraft flying under false paperwork (sure it was! *lol*). Very strange the air crew walked off the airport grounds and were never seen again - they didn't seem to mind their aircraft was being impounded
N168D is an aircraft purportedly owned (tho the owners changed more often than pigs farted) by Devon Holding and Leasing of Lexington, North Carolina. Devon Holding and Leasing is a front CIA company.
It's kinda amusing to see the antics, but more than obvious by both witness and ex-CIA employee testimony that these aircraft were facilitating serious offenses and the perps involved in these offenses are better off wiped from this planet.
