I know a commercial pilot who used that as a joke once and got in trouble. The plane in question had several pilots on it but the rest of the passengers didn’t find it funny for obvious reasons.
“We don’t wish to cause any alarm, but is there any one on board who is familiar with regular expressions, cron expressions and parameter expansion rules in bash?”
You joke but… There was an emergency nose high recovery out of San Diego airport where at one point the pilot had every passenger crowd into the first class cabin…
