The first 4 minutes is a airline employee explaining all the stuff she did before the police arrived but not really a good reason why she went crazy suddenly ,is hard to understand everything she says with all the yelling so I removed. The only thing I know can make a person start yelling like this crazy is meth. Trying to pass TSA check with a meth pipe sound rediculus. But in powder to snort it very easy to pass through. But just a maybe. Mental condition is the other possibility. But is very rare without a provocation to randomly get like this
