The first time I tried this in my Ventus, I was flying along
sideways with full rudder and level wings and heard a loud
"BANG!" After my heart stopped thumping, I figured out that
one of the gear doors had sucked open into the sideways
airflow. :-)

That happened to me once.Scared the hell out of me.

Another scarey bang was in a Puchacz on the winch when the cover, which is over
the rear seat adjustment bar, could not have been secure and flicked down and
hit the side of the fuselage. This was about six inches from my left ear and
was magnified by the megaphone shape of the hollow fuselage.

A third was in a Bocian, also on a winch when the rear canopy, which slid
backwards on rails, came unlocked, slid back and hit the rear stop. This one
was probably the worst because, a) we were about 100ft and starting to rotate
into full climb, b) in addtion to the "bang" as it hit the stop, there was a
huge, disorientating rush of air, and c) it took a while to work out what had
happened, take over from the pupil, (only his second or third winch take off)
and get the nose down etc.

However, one of the the worst I know of these type of incidents was a pilot at
my club who owned a Carmem and lost the complete canopy at about 4000ft agl. It
departing it caught his skull which bled profusely and a combination of blood
and the wind causing his eyes to run, made it extremely hard for him to see.

Once he worked out what had happened, his big concern was what else the canopy
had hit, tailplane for example. He considered baling out but, having checked
all controls decided to ride it down to the nearest field, successfully I am
pleased to say.

The farmers reaction to this bllod covered figure arriving at his door was, I
understand, unprintable.

Needlesss to say, all of the above (except U/c doors) occurred either as a
result of poor take off checks or mechanical faults.
