Triple X-ray #36 "A prop won't windmill on a Jab as there's a faid (fair) wad of compression. At a guess from experience it would take 140 knots before it will even think about turning over."
Good point Wally, I had (erroneously ??) concluded that due to the mentioned 'thumps', bangs and the way the lads immediately started searching for a paddock, that the donk was cactus; I noted the prop never even looked like budging during the descent. I demurred, due ignorance, to ask the question answered above, of compression ratio on the engine, just assumed (ass of u & me) it was seized. Don't know that a restart from that height after the 'orrible noises would have occurred to me. Paddock first, play later...
...but it has been a long while, happy daze.
