That's really indicative of a bad culture though. As a pilot, I use checklists and pre-flights religiously, and was appalled at the casualness and lack of safety consciousness eg on a sailboat or when scuba diving. I've never done sky diving (why jump out of a perfectly fine plane? :-) ), but the culture & attitudes you describe sound scary. Well, at least people have fun and selfies (and, unlike a careless pilot, they (most likely) only endanger themselves). /s
