Now you know why there was a flight engineer station for these birds!

Lou's point about fuel temps is an interesting reminder of some of the more arcane problems of real life aviating. A Pan Am 707 ran off the runway in Sydney in the 60's after a bird ingestion into one of the fans led to an abort before Vr, couldnt stop and ended up with its nose on a nearby road. Turned out the fuel density calcs were wrong, and the aircraft was way over weight, they were very lucky as they went through some of the HIALs and managed to not damage fuel lines or tanks with engines running and shut her down and every one got out unharmed.

Would be interesting if some one inserted a fuel density algorithm into the TOW calculator in the program in FSX.
