Carson
Carson is the Company that actually does the update; the S-61 composite blade is quite well known as the "Carson Blade". Cougar helicopter out of St John's Newfoundland operates a Carson bladed aircraft and I believe that they did some of the engineering work for the integrated glass cockpit as well?
Anyhow the point is that yes in fact they will be breathing new life into the S-61, and that is great. The S-61 should be universally recognized as the DC-3 of helicopters.
