(2) Result:
(a) After achieving zero airspeed, the
aircraft will begin a tailslide until control

approximately 60-100 KIAS (negative
airspeed)
(b) At this point, the aircraft will swap ends

abruptly and may overshoot the
vertical by as much as 90 degrees in
the pitch axis.

From the 80-90 degree departure,

controls from the neutral position
(c) The engine may have its airflow
interrupted causing a compressor stall
NOTE: Nearly all of the flight-tested
aircraft developed some type of engine
stall under these conditions.
(d) After one or two nose-low oscillations,
the airspeed will increase to a nose-
low dive recovery
(e) Adverse roll and yaw oscillations are to
be expected if the pilot fails to maintain
neutral controls throughout the
departure
