Relying on military pilots to tell the government what they need for national defense is folly. They are in no position to make such assessments.
Perhaps, perhaps not, but here is a little quote from the investigation into the recent V22 mishap
Q36 (PILOT ADVISOR): And sirs, one last question, how have the CV-22s performed since they have been over working under your Task Force?
A36 (WITNESS): Phenomenal, they have been value added. I want to say 13 or 14 missions, don’t quote me on the number, but over 10 missions--certainly over 10 missions to include last night where they performed and in several cases although there are some mission profiles where they are
not as capable as the CH-47 platform, there are other mission profiles where they have proved to be much more capable and, in fact, the desirable platform for execution to include A casualty evacuation mission we had to do during daylight and because of their speed of flight they were able to arrive in the objective area, pick up the casualty and return to the medical treatment facility twice as fast as the CH-47 would have been able to do it.
There are sentiments similar to these all over the record from a diverse array of sources including pilots, operators, commanders, etc.
