This intersection is the coffin corner, or more formally the Q corner. [3] The above explanation is based on level, constant speed, flight with a given gross weight and load factor of 1.0 G. The specific altitudes and speeds of the coffin corner will differ depending on weight, and the load factor increases caused by banking and pitching maneuvers.
Ruby Franke, the Utah mother of six who branded herself as a parenting expert and garnered millions of subscribers to her now-defunct YouTube channel, "8 Passengers," was driven by "religious ...
Pilots had to adjust to the U-2's unusual combination of jet engines and enormous, high-lift glider wings; because of the "coffin corner" they learned of the need to pay complete attention to flying when not using the autopilot. [61]
The plane was approaching the coffin corner of its flight envelope, when the turbulence was encountered. After that near disaster, the stall mach buffet margins were widened on all jet aircraft, to preclude a plane getting into that situation again, where severe turbulence narrows the "coffin corner" margins so severely that the pilots do not ...
The Alaska Airlines pilot who guided 171 passengers and four flight attendants to safety when a door panel blew out of the aircraft wasn’t aware of the mid-flight emergency — but knew ...

The captain then checked the stabilizer trim setting; it was set at the correct 3.5° nose up. The aircraft seemed to stop pitching up at 15°, the gear was retracted and the plane seemed to return to a normal flight condition. at 400 ft, the aircraft began pitching up again, from 15° to 18°.
After reaching FL410, the airplane was cruising at 150 knots (170 mph; 280 km/h) indicated airspeed, barely above stall speed, and had over-stressed the engines. The airplane's antistall devices activated while they were at altitude, but the pilots repeatedly overrode the automatic nose-down that would increase speed to prevent stall.
