threemiles
thanks for the information
slowing for turbulence is about 285 knots (mach .76 or so)
this could account for some reduction in ground speed.
the altitude changes are of great interest too
further reduction in ground speed may indicate highly reduced airspeed approaching losss of control
the turn might be away from the storm.
however I don't see the original radar plots or anything else.
I can imagine loss of one or both engines, reduced speed, unable to maintain altitude etc. loss of engine due to hail
we shall see. but thanks
