"An aircraft being used for aerial shots of the 2012 Olympic Games had to make a forced landing at Cambridge Airport.

The King Air B200, which was being used as an airborne relay station, had to land after suffering a loss of its electrical system.

Operators, ASL of Belgium, said the pilot had to navigate on Saturday night using only charts and a compass."

Someone asked aerlier in Chat what this aircraft was doing circling overhead the Olympic Park.  Now we know:

"The aircraft was used as a TV relay station for the Olympic Games in London."

I thought this comment was amusing:

"The crew noticed a total electrical failure at the end of their mission"

Pretty hard to miss.  :)
