Now what is this C.30A doing in a decidedly un-English landscape in 1938?
Photo on p.91/108 shows Cierva C.30A PH-ASA c/n 707, ex G-ACVX, which crashed at Oostwold near Hoogkerk on 25.5.38. Flown by De Velden it crashed at 1900 hrs when en route from Rotterdam to Appingedam near Groningen. A number of other suggestions were put forward , notably LeO C.30 F-AOIO (ex Avro C.30A G-ACWI) at Rouen on 29.5.38. At least the landscape clues seemed to give readers the right general ideas!
