Yes, I got to play with the Sioux (WAB-47G3B-1 catchy title, eh?), a splendid and reliable machine. Even with a Stokes litter either side and the doors off it would cruise at 70kts – which beat the 55kts the Hiller could manage. Flying into any sort of wind you could not fail to notice surface transport going faster! Time to spare? Go by (Hiller) Air!!
