Hunt3r, have you heard something about a DoD contract then?

Dave, i think the fairest comparison (when i get around to it) would be to compare machines capable of landing in the same ground box area. This would allow the benefits of better FM through such things as reverse velocity utilisation to be evaluated in a holistic way.
