The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration , at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb.

March 6 – The last flight of the SR-71 Blackbird takes place, when Lieutenant Colonels Ed Yielding (pilot) and Joseph Vida (reconnaissance systems officer) fly U.S. Air Force SR-71A serial number 61-17972 from Palmdale, California, to Washington Dulles International Airport in Virginia, setting a Los Angeles, California-to-Washington, D.C. world record time of 1 hour 4 minutes 20 seconds at ...
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 ...
