A Diamond DA42 MPP Guardian has been conducting vital surveillance missions throughout the 2012 London Olympic games, acting as a fixed wing remote sensing platform.

Equipped with a FLIR Systems electro-optical infrared camera, secure data links and specialist communications, the Diamond aircraft is able to stay airborne non-stop for more than eight hours per mission.

The aircraft type has already been used several times for the same purpose during the Austrian Donauinselfest, an outdoor music festival which takes place every year in Vienna.
