B-52, It keeps going and going...

...and Evan thinks the 737 has seen it's day.

PS: I would THINK the great engineers would change this to a four-engine aircraft???

From a pure thrust perspective you could probably get away with two, although there are a number of reasons not to. (e.g. rudder authority) However, moving to four seems necessary to get most of the touted advantages. If nothing else, to get the efficiency improvements you want a high-bypass design and that's just not going to fit in the existing 8-way nacelles. Also, all else being equal having 4 engines instead of 8 gives roughly twice the dispatch reliability...

Would you care to explain that? Do you mean making it a twin?

Hell. why not with one? Just stick a Saturn rocket or some such on its back (3MT-style) and off you go!

Why not zero? It would make a really badass glider, considerably decrease maintenance costs and points of failure and, more importantly, eliminate the risk of stupid pilots monkeying with the power levers.

Explanation: Ocelot said, "From a pure thrust standpoint"

Context matters.

In that context- (that, and Flyboy's suggestion) makes sense.

...and yes, Ocelot is saying that there are engines out there with enough thrust where two would propel a B-52...I don't doubt that...
