A *theoretical* aircraft wing can stall at any airspeed. Above a certain airspeed, any *real* aircraft wing will experience structural failure prior to reaching critical angle of attack. I suspect, but don't know for certain, that a real 737 wing, which was traveling though the air at 5000 ft MSL, with no extraordinary tailwind, at an IAS which resulted in a groundspeed in excess of 300 knots, would experience structural failure before exceeding critical angle of attack. For certain, it would take extraordinary control inputs to force that wing to stall.
