No problem, right? You casually scoot past your seat neighbor, make sure that you aren't queuing in the front of the plane for the lavatory (as to not hack off the flight attendants), and get ready to void your own personal fuel tank in the tiny, cramped restroom. And then, the plane depressurizes. It sounds like a scenario out of 24—and it very well could be. However, in months past, this wouldn't be much of a problem. You might be a little scared, perhaps even confused, but it wouldn't be that big of an issue to grab the oxygen mask and breathe in some sweet, lifesaving air while waiting for the situation to sort itself out.
