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?
