Interestingly found a signed copy of 'Impact Erebus' in an oppie y'day.
GV had signed it to one 'Mervyn' who seems to have been a pro aviator in some capacity, as there were quite a few related books in a batch, including the L'Estrange highly slanted one. GV's book is full of insights that no other person involved in the enquiry could have come up with. The sad thing about GV today is the terrible things that a stroke can do to your senses. Remember your aspirin prooners one and all.
