220:. Piasecki had limited pilot experience; the PV-2 was tethered to the ground as a safety measure, but the clothesline he used broke. He towed the helicopter behind his car in October 1943 to Washington, DC to demonstrate it to federal government officials; because the wheels had no bearings, he had to stop every 10 to 15 minutes to cool them. When asked to show his pilot's license following the demonstration in Washington, Piasecki admitted he did not have one and he was issued the first helicopter pilot's license on October 20, 1943, by the

At approximately the same time the HRP-1 and HRP-2 were being developed, the Navy commissioned
Piasecki to design a smaller tandem-rotor utility helicopter; the resulting prototype, which Piasecki called the PV-14, was designated XHJP-1. These went into production as the

An evolutionary follow-on design to the HRP-1, designated HRP-2, used an all-metal skin and switched crew seating to side-by-side instead of tandem; however, the limited power meant only five were built, all for the Coast Guard. In 1949, Piasecki provided the
