You need to be careful not to touch buttons or pull levers when you are around expensive equipment. One man in South Africa found this out the hard way when he was in a jet with South Africa's Silver Foxes (their version of the Thunderbirds or Blue Angels). He accidentally pulled the lever to the ejection seat during his flight.
Fortunately, he was in a good position to eject and escaped with only minor injuries...but what a ride!
