Nick,

Thank you for stirring the pot. This group has been pretty dry lately.

I think in your your zeal however, some of your data has become some
what skewed. When making comparesons between aircraft I usually try to
use data from the same source. Comparing data from different sources
only leads to errors. The source for the data I am using is from:
DEPARTMENT OF THE NAVY, NAVAL HISTORICAL CENTER and the Naval
Helicopter Association.

For those who might like a (hopefully) objective view of the possibilities of
upgraded conventional helos vs. tiltrotors or the like to meet the proposed
Future Transport Rotorcraft spec, and the technical and tactical issues raised
by the spec, I'd recommend reading the following:

The article on heavylift rotorcraft (as well as the proposed ATT) here is also
useful:
