JOINT BASE ANDREWS, Md. - U.S. Army Special Forces soldiers from the 7th Special Forces Group (airborne) use the Fast Rope Infiltration/Exfiltration System to quickly evacuate the landing area. A Special Operations UH-60 Blackhawk Aircraft lowers the FRIES rope system to the soldiers, who latch on as a group and are airlifted, suspended below the aircraft. The demonstration is part of the Joint Service Open House 2010 here May 14-16. (U.S. Air Force photo by Senior Airman Melissa V. Brownstein)
