anything 'other' than high speed aerodynamic stresses that could do that,?
Whatever you mean by high speed aerodynamic stresses... lots of things could. A kniife like object striking it maybe...
Water is hard when struck at any speed.
Depending on how an object is supported acceleration or deceleration alone can achieve surprising things. Aerodynamic s doesn't have to come into it, high speed or not
so proof of nothing yet IMHO
NB. Aerodynamic Forces create stresses (and strains) on objects... per se there
is no such thing as an aerodynamic stress, other than maybe between molecules
of air.
