Ok, I'll play the game and just speculate.

Flex (Bombardier Aerospace) is profitable. Fred has cut expenses to the bone.

Bombardier needs to move aircraft, get them off their books to show sales.

So, simply sell them to Flex, which makes Bombardier look better and stronger financially. Showing positive sales figures during these times helps get investors fired up.
Flex gets to write them off for depreciation and pay less taxes to the Feds. Plus, if a union tries to look at the books during negotiations, Fred can cry poor mouth.

I can't believe I'm not wealthier than I am!
