Hi,
It is essential to keep the standard high nothing can be neglected
it is not a kindness to overlook slackness or mistakes, it is really great cruelty to do so cruelty to wives and relatives of the man you let off and his shipmates and to yourself.
There is no margin for mistakes in submarines; you are either alive or
dead'!
These words, spoken by Admiral Sir Max Horton when Flag Officer
Submarines in 1941 to all submarine officers and men in Malta, carry a universal truth for all mariners, not just submariners.
Methink this can also apply to the airliners pilots
