Peter thanks for that post. Terrible that you lost your Dad under those circumstances.
None of us will ever know what went on between the crew members on that fateful day. It is easy to say that both altimeters were miset which is clearly factual.
However the reasons behind that altimeter miset are something that we now will never know.
Your Dad defended his country in time of war (as did mine) and for that we should be very proud of their bravery and achievements.
Flying aircraft in those days was not quite the piece of cake it is these days. Some will disagree with that statement but I stand by it.
Kind regards
