Over the past several days, the DoE has been flying their rotary wing Aerial Measuring System to scan the metro Phoenix area for background radiation prior to the NFL championship game.
The helicopter, N411DE, is a Bell 412 modified to support the radiological survey, search, and mitigation tasks.
The mission has been completed and the aircraft is back at Nellis AFB.
