This accident is a perfect illustration of how the pilot is unlikely to know
what is critical if limits are exceeded. The ASW20C did not flutter, and
did not break up in flight; the first failure was loss of control.

Was there any discussion at all about the possibility to attempt
controlling it with the flaps ?

Not that it is likely to help, possibly just the opposite, since
you'd be even more in exess of the (lower) Vne for flap positions
other than fully negative.

But if it is really out of control one would imagine trying anything,
if only as a last-ditch attempt to stabilise things a little and be
able to bail out.

Bailing out at 200 kts can't be exactly easy either.
