Hi Preon,
I had read about that somewhere in one of my reference books, but I forget which one now. I'll see if I can dig up something on it. Others may also know about it and can advise.
Argentine Canberras suffered the same salt-water corrosion problems when flying low-level over the South Atlantic during the Falklands War. A few suffered flame outs and had to abort. I think some Peruvian Cans also had the same problems operating from the coastal base at Pisco over the years.
Will keep you posted on the book, thanks for getting in touch.
Steve
