Cierva W.11 Air Horse VZ724
Cierva W.11 Air Horse VZ724 / G-ALCV (msn W.11/1 ), which first flew on 7 December 1948 as G-ALCV, was marked with the Air Ministry serial VZ274. G-ALCV / VZ274 crashed on 13 June 1950, claiming the lives of Alan Marsh (chief test pilot) John Jeep Cable, (Ministry of Supply test pilot), and Joseph K. Unsworth (flight engineer).
