Both pilots of the Alouette III from the National Air Force of Angola survived the crash with some injuries during a display marking the 39th anniversary of the Air Force at Saurimo Air Base on the 22nd January 2015. From the video it looks like the pilots were performing maneuvers over the limits for the helicopter and it suddenly disintegrated in mid-air.
The Alouette II was damaged beyond repair. No one was injured on the ground. A commision of inquiry was set up to investigate the crash. More information will be published when it is made available.
