Boeing





The second helicopter ever flown in the United States was the product of the predecessor company of today 's Boeing Helicopters. The machine was the PV 2, which acquired its designation from the name of the early firm -- the P - V Engineering Forum which was founded by the legendary Frank Piasecki .
