Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, making it very difficult to keep an airplane in stable flight. Because the stall speed is the minimum speed required to maintain level flight, any reduction ...
At the top of the B-47's envelope, about 35,000 feet (11,000 m), it was in "coffin corner". [49] That means that at this level, which produced the most range at most weights due to fuel consumption, there was an envelope of 5 kn (9.3 km/h) between maximum mach and stall speed.
Coffin corner may refer to: Coffin corner (aerodynamics), an unstable combination of speed and altitude; A position in a bomber formation combat box; Coffin corner (American football), a strategy used by a punter in American football; The Coffin Corner, a magazine published by the Professional Football Researchers Association
Altitude envelope (H-M diagram).Contour is load factor. Turn rate envelope, described in an E-M diagram (doghouse plot). Contour is specific excess power. A doghouse plot generally shows the relation between speed at level flight and altitude, although other variables are also possible.

A perfect coffin corner kick is one that goes out of bounds just before either orange pylon located in the front of the end zone. The punter tries to place the ball so that it lands out of bounds or is downed on the field by another member of the kicking team anywhere inside the 5-yard line without touching the goal line, thus forcing poor ...
