This very unfortunate accident reminds me of a similar one PanAmerican had at KSFO, with a B747, in the very early seventies.
Departure from a shortish (01R) runway, and takeoff calculations/V speeds done, with the expected use of flaps 20, however flaps 10 selected instead, and the error not caught.
The aircraft rotated at the end, with extensive damage to the lower fuselage and tail.
PanAmericans 'fix', so this absolutely, positively would never happen again, was a 'configuration check' as the last item on the before takeoff check, and that it must be done while lined up on the departure runway.
The configuration check consisted of....
Flaps/V speeds correctly set for the departure runway
Spoilers down
Trim in the takeoff range, correctly set
Compass headings all agree with the departure runway.
Two other airlines that I am aware of also adopted this procedure as well.
I wonder, were the flaps correctly set for the runway used with the MK aircraft?
I suspect we will find out sooner rather than later.
A very sad event, nonetheless.
