The "coffin corner" is that part of the flight envelope where the
combination of altitude and speed puts you just above stall (IAS) and the
aircraft's aeroelastic limit or flutter speed (TAS).

I don't recall seeing a flight envelope graph in a glider flight manual or a
normally aspirated pistion-engined airplane - I've only seen then in jets.

Flying high in wave can certainly get you there!

High altitudes get you into the coffin corner especially with the higher
