Why is this impressive? Either they beamed it out through satelites, which is notoriously hard from an unstable platform on big waves, or they recovered the saildrone and obtained the footage directly which is equally impressive in or around a hurricane.
All around if the dating of the footage is correct it is very impressive to me.
(I actually live in Chelyabinsk)
That must have been absolutely amazing.
Did you see the initial airburst itself? What were your thoughts / how would you describe your reaction as the event unfolded?
