I am rather surprised it has less than 5.000 views. I am not a pilot whatsoever but a management consultant and lecturer and I can only say that many executives can learn from aviation field thus I like to use such examples in my lessons.
It is interesting to observe the struggle to find out what and why happened.
Just one question - didn't DC-10 have some MFRD type of radar back in 1979?
