A lot of Hamburgers are getting they're pants wet because of a squadron of swiss military jets taking part at the harbour fest.
Pilots might have gone under the permitted flight level and out side of the approved airspace (to close to downtown/Lake Binnen Alster).

You got to hand it to these people, they know how to ruin a good party
Guess we can all drink tea next year and watch boats bobing in the water.
It should be noted that Switzerland is the partnering country at this years festival and they contributed the airshow. What a way to treat a guest for 3 days!
