AFRL Commander's Challenge
An Eglin Air Force Base team member attaches rotor blades to a remote control helicopter during the 2017 Air Force Research Laboratory Commander’s Challenge at the Redstone Arsenal in Huntsville, Alabama, Feb. 26. The team’s concept was to use the helicopter to drop a canister, with auto rotating blades meant to slow its fall, in order to resupply troops. (U.S. Air Force photos by R.J. Oriez)
