Quote: German authorities are investigating how a man was able to spend four hours partying alone in his underpants on a military jet used by Angela Merkel.
The 24-year-old entered the cockpit, pushed buttons randomly, deployed an emergency slide, and sprayed a fire extinguisher over the plush interior.
Police tried and failed to persuade the man to leave with a megaphone.
They found a bag with his identity documents and, allegedly, ecstasy and marijuana near the aircraft.
The incident, at Cologne airport on 25 July, was brought to a close by a police dog biting the man in the leg. |
