SERE submerges aircrew for proficiency
An aircrew member lies submerged in a shallow water egress trainer chair during rotary wing water survival training at Hurlburt Field, Fla., July 18, 2017. The SWET chair tests the aircrew member’s ability to breathe using a helicopter emergency egress device and successfully get out of the seatbelt while underwater.
