The Brazilian Air Force and KC-390 designer Embraer continue to test the new Brazilian tactical transport plane. The program completed a major phase recently, dropping 18 parachutists in free fall from the aircraft from 12,000 ft. The parachutists initially used both the rear ramp and side doors to exit the fuselage. The Brazilian air force has begun operational testing of the Embraer KC-390 transport / tanker aircraft at Campo Grande air base.
