Where did the airplane come from?

This may have already been discussed, but I keep seeing a larger airplane with a sun on the tail in friends' Springfields, and I'm not sure where it came from. I don't think it was available during this event (if it was I missed it).

Does anyone know where that airplane came from? I tried searching a few sites for it with no luck. Is there a list somewhere that contains all of the aircraft available? Thanks in advance.

Edited to add more details.
