Mike:
Sorry it took so long, was away.
More difficult to find as it was actually a derivative of the
Sparrowhawk called the Owl (apparently the L is an extra letter) which
was built specially for the Raspet Flight Research Lab.
Believe a lot was learned about deceleration using BRS. The pilot was
still strapped into the seat pan when he was "ejected".

Post flight analysis of the data indicated that during the
nose down attitude, the wings separated from the airframe at
approximately 162 knots. The flight
engineer stated that the glider was equipped with an airspeed indicator
that indicated a maximum
airspeed of 105 knots. The stop-point for the airspeed indicator was
just beyond the maximum
indicated airspeed. The pilot was unaware that the "never exceed" speed
of 123 knots had been
breached during the descent.

Jim,
When was the incident below and what were they trying to do. Any links
to it?
Please remember that the Raspett team took a Sparrowhawk over redline
because they installed an ASI with a stop at the redline. Broke the
wings off. BRS deployment ripped the pilot in the seat pan out of the
glider. Pilot used a conventional chute.
