No idea but a bit of a trick question, 1st response would be, 'from what height?, and at what weight?, props feathered or in pitch?' Having said that its a commonsense choice, put it down with power asap. Being quite a slippery design with a relatively small span it probably doesnt have the best glide ratio, however the DH Mosquito museum at St Albans, may have some of the perf. data that someone could work out the answer to the question. Being right at the front in a wooden aircraft he'd be first at the scene of the accident with little substantial protection, so again a sensible choice not to ride it in. Unless he's a driver in 633 squadron during the filming........
