Window, and chutes of various sorts...
Hi Cliff,
Aha! I think you have just solved a mystery, probably brought about by loose descriptions in the biographies etc. There was a honking great flare chute in the rear of the Lanc, or at least some of them (seen the pics) and I think that some authors have concluded this was also used for window. But your mention of the mini chute next to the FE is not the first time I had heard of this. So, unless there was some huge difference between the marks of Lanc, with some not having the FE chute, then I think that solves the issue.
Reg, I have just dug out a reference to the Lanc oxy system - apparently there was a point by the 'flare station' but from what you say, no-one ever wanted to be there!
Cheers,
Dave
