anyway it was a short flight and never got to ask him why.

I began thinking of TODA TORA ASDA BALANCED FIELDS CLEARWAYS etc all being calculated from a certain point and would these be invalidated if you started your take off run say 309m earlier , airfield and terrain dependent of course ??
Maybe the geezer just misheard the reason for the backtrack?
