Makes me wonder.
I'm sure many of you have seen that film of ( I beleive it was NASA ) 727 test landing, where the tail + last few meters of empennage is ripped off, due to excessively high sink.
The test being conducted was a high sink landing thing, except that the pilot exceeded parameters.
I am wondering whether the test was done because of the specific problem with the 727 discussed here ?
( i.e. research into the causes...)
