Double Eagle II Airport, New Mexico (West of ABQ):
Coming in for landing was this Bell LongRanger:
I asked a guy who was securing the helicopter, about the configuration.
I thought it would be some kind of MAD device, and he confirmed it. Designed by the US Navy, and transferred to civilian operations, this is the second iteration
of this apparatus; it is employed to search for unexploded ordnance on the fields West of the airport, which used to be a USAF bombing range. There are 5 MAD's in the crossmember, two real time GPS transmitters, there is a radar altimeter / and or laser device to help keep the helicopter at the same altitude (very low by the way) over the terrain.
I was told that they manage to scan approximately 500 acres per day, and anything that is detected is superimposed on a topo map of the region, for further exploration and disposition / deactivation by EOD.
Saludos,
Tulio
