I agree with the comments regarding the unresolved position of a number of airline disasters, makes you wonder, doesn't it!
In regard to the Concorde crash, as I understand it, the most critical time for the undercarriage/wheel combination is the actual rotation to flight attitude, putting a very high downward vector when the elevons rise on command.
Surely the answer is to relieve this very high load, which is at least partially to blame, is to fit Cannards.
Used primarily for this 'lifting of the nose for rotate', they can be used for all 'low speed' flight, and then parked at neutral during cruise, and used again for the approach and landing.
Seems it would make them much more resposive at lower speeds/altitudes, but not detract from their normal flight profile.
Been done before on other aircraft, for similar reasons, to good effect.
comments! - seems to simple!
