For a while I have been wondering why there seem to be no
airplanes with a low wing and a high tail.

Duchess and Seminole come to mind.


Not to mention the DC-9 and MDxx variants
or the KingAir200

The deep stall first got real attention in the crash of the BAC1-11
during test flying. The full official report is included in Brian
Trubshaw's book Test Pilot. The configuration of the BAC 1-11 and the
DC-9 were very similar. The 1-11 descended almost flat with little
forward velocity until it struck the ground during a stall test flight.
All the crew were killed.

For test flying after the crash a tail parachute was installed. Part of
the trouble was the use of servo-tab elevators which at High AoA became
almost useless.

Both aircraft went on to fly safely for many years.
