There seems to be general assumption expressed here - amongst so much other complete BS and a little interesting information - that the left main gear has been punched up through the wing. So far the only source of this damage report seems to be the one photo from 3/4 front showing 'something' unusual on top of the port wing. Looking at that 'something' isn't it perhaps simply a deflated escape ramp from the open overwing exit there rather than top wing skin panelling burst open from below?
Except the 737 does not use escape slides. In an evacuation pax would slide down the flaps onto the ground.
