At some point in its development, the "exhaust" from
the GAU was enough to cause an engine flameout in flight.

It is a crazy bit of kit.

Was it also fact that the plane was actually slowed ('measurably', I
know 'Every action has an equal and opposite reaction' so even a
single bullet fired forward would have an effect to a tiny degree))
when the gun was fired?

Yup, I believe so... Its not an aircraft with a large gun built in, its
a large gun with wings and an engine added!

Yup, 'crazy'. ;-)

And considering how heavy they must be (gun, munitions, armour) and
how small the wingspan looked, it was interesting to see how slowly
they could fly when doing their 'touch-and-goes' around us. ;-)
