I've been on plenty of planes before
Security? It's okay, but annoying when they ask you to open your trunk and you can't find the stuff that they think is suspicious/dangerous. They took away my scissors once
Food? Bleurgh. I throw away 3/4 of the stuff they give us.
Odds that you'll be stranded on an island? Just don't think about it ... even if it's one in three billion your plane just might be that one. >.<
