OTTAWA—Senior military officials have revealed there was a “conflict” or “competition between a Cyclone helicopter and its pilot moments before the aircraft known as Stalker 22 plunged into the water off the coast of Greece in April.
The revelation came Tuesday as the Royal Canadian Air Force announced it was lifting an “operational pause” imposed on the rest of the militarys Cyclone fleet after the crash, even though the reasons for that conflict remain under investigation.

Rather than turning off, the auto-pilot started to work against the human pilot before crashing into the water at high speed. All six Armed Forces members on board were killed, representing the largest single-day loss of life for the military in more than a decade.
