To prevent this happen I have 4 x microswitches and green/yellow leds to warn 
unengaged
shootbolts.
Those leds are just in sight and it is almost impossibe not to see those yellow
ones.
During T.O.  I check if the ASI is operative and the leds are just beside it.
Secondly, some of you may remember the pip-pins which secure the door levers to
the door lever guards to prevent human errors (= unintentional inflight door
opening).
