If Boeing Built A Five Engines Jet In The 60's?

Wed Jan 03, 2007 1:07 pm

I look at the 707, 727 and 737, and got to thinking. What if Boeing had built a five engine jet during the 60's. The jetliner would have a t-tail and it's engines on the back like the 727? It would have five JT3-Ds or fan version of the JT4, it would be 200 + feet long with a wing span of 162 feet a height of 40 feet. It's cruising speed would be mach 0.94 with a max speed of 0.98. It would have triple slot flaps and the same section 41 as the 707. So what do you think? Big grin

Boeing built an 8 engined jet in the 50s so 5 engines wouldn't be a challenge  Wink
After Monday and Tuesday even the calendar says WTF...

Quoting 747400sp (Thread starter):
It's cruising speed would be mach 0.94 with a max speed of 0.98

In the 1960s, she would be slurping so much fuel she just might make BOS from LGA at those speeds  smile

Convair built 385 10 engine airplanes in the late 40's and early 50's.
It was called the B-36

Some Dornier flying boats had even more, like 12.
