That works well in flight where air lift loads on the inlet are significant, but I would think that ground friction loads against the nacelle would stop the engine so the wing would try to overrun it. At any rate no complaints about the design when the aircraft intersects something other than air

Lomapaseo, this is somewhat out of my area of expertise (I've never worked structures), but my understanding is one of the design scenarios is an overload due to a wheels up landing - you want the engine to go up and over rather than under for obvious reasons. However CONSO is right - without knowing the exact angle and speed of impact it would be near impossible to get it to work 100%. Oh, and CONSO is also correct about the 'dry bay' in the area of the wing where the strut attaches (also helpful for uncontained engine failures).
BuzzBox, thanks for the clarification - I was unfamiliar with the limitations of the Doppler based windshear system in the desert.
