A 747 flying around on what looks like a flight check maybe after some maintenance? Anyone know a tail number any other info?
Operated by Singapore Airlines
Happens to be the 1000th 747 built
Theres been a few Singapore Airlines 747s down in So Cal.
Southern California Aviation LLC, based in So Cal Logistics Arpt performs maintenance on commercial aircraft including Singapore, so probably got fixed up and tested before going back into service.
