Any chance those are temporary Bombardier test flight, or pre-delivery tails that rotate aircraft? Aircraft manufacturers normally keep a block of tail numbers to use for pre-customer delivery flights and recycle them as aircraft roll off the line. Doing Bombardier deliveries a few years back there were temporary C- registrations that were peeled off when we accepted the aircraft and certification was complete. As the Richardson address is also for Bombardier US, any chance they are just flying them in those N#'s within the US for completion, interiors, etc? Some of them were dated back to Jan 2009.

A cursory glance at the FAA registry also reveals a number of N__ZZ tail numbers in TX and DE. Most likely Bombardier's block tail numbers for factory trade-ins being resold on the market.

Nice rumor, though. The better half is on furlough from Flex... would be nice to go back to being DINKs and not SINKs

Things that make you go Hmmmm...
