With all due respect to my learned friend but the idea that
It's well known that cameras can distort and give a false impression.
is just luddite horsesh8t.
AAIB/BEA/NTSB have all issued recommendations on introducing crashworthy video crash recorders onto aircraft without FDRs. Are they too stupid to know that "well known" fact?
Bell and now Eurocopter are now offering such systems. Have they failed to spot this "well known" flaw in their plans?
