Anyone considering windscreen failure/rapid decompression would do well to read the
AAIB report for the 1-11 incident to G-BJRT.
That happened as the A/C was passing FL170; imagining the same scenario at FL380 is thought provoking.
In that incident,
"the flight deck door had been blown onto the flight deck where it lay across the radio and navigation console".
Would a current-day reinforced door remain in place after a rapid cockpit decompression at FL380?
