Back in January, in this post, I described an interesting visit to the Sikorsky Aircraft plant in Stratford, CT - including a discussion of the X-2 Technology demonstrator.
Last week (as recounted here) the aircraft surpassed the standing record speed for helicopters by achieving 225 knots in level flight. The new record is, for the time being unofficial, as all of the FAI protocols were not applied.
So somewhere, Mr. Sikorsky is smiling. And, meanwhile, could someone explain to me again the rationale for the V-22 Osprey?
