can you fly a 747 on only 1 or 2 engines?

Yes but your jumbo jet mabe fall down because on 2 engines ald full fuel safe . If you have no fuel and more luck it true

Long runway

A 747 can fly with as little as 2 engines... one on each side... if you fly with only 2 engines on the same wing you're pretty much screwed unless you are at gliding distance from your runway and can land on Idle power... however if you have 2 working engines (one on each wing) you better find an airport and land as soon as possible... Power is decreased by over 50% and altitude will be lost quickly...

yes tht can  8)

Depends what you mean by fly. I'm not sure about maintaining height on 1 or 2 engines but the 747 makes a pretty good glider. This was proved on one occassion when a BA (I think) 747 full of passengers flew through a huge cloud of volcanic ash. This stopped all the engines but it glided for several 100 miles I believe before they were able to restart them. I seem to remember them saying at the time that the glide ratio was as good as some sailplanes.

I found this which might throw more light on the subject. http://www.transportblog.com/archives/000850.html

Thank God for Rolls-Royce Engines!

You'll notice that if all engines fail there's not enough power after a minute or so to drop the gear on a big jet, you have to get it down fast!

Yes, it was a British airways 747-236, Regestration G-BDXH (C/N 21635). The incident occured on the 24th of June 1982, over Indonesia, when the aircraft accidently flew over an erupting volcano!

'XH first flew in March 1979, and was delivered to BA in the same month. It was retired in 2001, and then sold to EAC. They retired it in 2004, and it is curently stored at Hurn (Bornemouth) Airport (EGHH), without engines.
