Helmets?
no don't worry about 'em atall. just like this bloke didn't.
The a/c fell on its stbd side, note how far in the side has been puhed, no helmet, pilot killed instantly when his head slammed onto the bitumen after a fall of twenty feet or so.
This machine has been stood back up on still intact skids during the investigation, note the rocker covers on the ground to allow access to check for jammed valves.
