RE: First Transcon Flight - Opinions

For comfort a 767 is good. If you wish to look outside then you might want to fly in something else. The dyhedral on the 67 is great and the view of the wing also great. It is difficult to see outside other than the wing. The 747 in first is still wonderful as is an <acronym title="Air Madagascar">M...

The Engine Would Flame Out.

In the case of a front fan engine if you changed the pitch of the fan blades for reverse thrust the compressor would be starved for air, and the engine would just shut off, except with power plants whose fans don't have blades right at the shaft (inner diameter).
