What are the 12 most annoying things flights instructors do? Obviously, flatulence in the cockpit would be a big no-no. “Sorry about that. Blame it on the burrito. Let’s crack open the window for just a moment.” Apparently, however, that wasn’t one of the Big 12 as posted by flying students on Reddit. If you don’t know what Reddit is, it’s akin to an online bulletin board. A social networking site, it allows users to post questions, and then it allows people to respond. Wish I would have thought of it. It kicked off in 2005; the brainchild of two University of Virginia roommates.
