not enough water.... post 2056 Phil Golin
Phil to reply to your assertion about not enough water content strikes me as "denial" ,The Met physistists swore there wasnt enough water at 25000ft to cause a Viscount complete 4 engine shut down over the Alps in1958. Their figures were out by an enormous factor , something like100/1. So we had to modify all Bristol Proteus engines as a result.
