How about this for deck quals?:
H Frank Gregory, now a Lieutenant Colonel, subsequently demonstrated the XR-4 from a platform mounted on the tanker SS Bunker Hill. in May, 1943, 24 landings and take-offs being made. Additional tests were conducted in July 1943 with the XR-4, and the first YR-4A, operating from a stern platform on the troopship SS James Parker. In the course of this 20-hour test, the two helicopters made 162 landings and take-offs.
That was before they had NWP-42!
To my former shipmates from HC-6 (LCDR Al Jacka), HSL-32 (LCDR “Buzz” Buzzell) and HSL-44 (LCDR Marty ??? (age…sorry)), this one’s for you!
