It appears to be an airshow, if it was post-maintenance , then that seems to be an addition.
Both pilots in intensive care , sadly
Hope they both make a full recovery.Very sad.
It seemed to be doing a very hard left wing-over, remined me unfortunately of that awful B52 crash pre-airshow where the pilot pushed things too hard.
Whether this was intentional or not, we've yet to find out, but its sad we have 2 guys in a very bad way, and a formidable aircraft in ruin .
