well in my day it was always no smoking within 12 hours and no drinking within 50 feet. Always stuck to that rule and not scratched an aircraft in 47 years
As dodgyoldfart says, in the military of the 60s it was not uncommon for a pilot to have a little sharpener prior to a trip. As for a night deck landing, several swift ones post flight regardless of what time the morning push was scheduled was de rigueur! From HM's service to civvy street was a natural progression and does a leopard change it's spots? Hardly! So the nearest watering hole for a debrief post flight just comes naturally. There but for the grace...etc. Glass houses and stones comes to mind!
