I'd be perfectly calm if some drugged up passenger tried to open the door midflight, because I know its not possible. A single human does not have the strength to overcome the differential pressure on the door. Bravery has nothing to do with it, it's knowledge. I have 100% confidence in the laws of physics continuing to work!
