I'll throw in my "strange things flying on planes" story.

An ex-girlfriend worked for a large yogurt manufacturer. One of their manufacturing plants had an issue with "the culture" (the bacterial culture used for fermenting the yogurt, that is). She said product was exploding out of containers in the incubation rooms.

The operators decided to sterilize the plant and bring a sample of bacterial culture from another of the company's plants. An employee was paid to ride in a first class seat beside a temperature-controlled container of bacterial culture.
