High-flying drone almost collides with Edmonton police helicopter

One night in July, Const. Brian Griffith was responding to a call in Air-1, the Edmonton police helicopter, when he saw somethingflying near him.

At first he thought it was a bird, but on closer inspection he realized it was a high-flying drone, white with red lights and a rotor at each of its four corners.

"We were flying at about 180 kilometres an hour, 1,500 feet off the ground," Griffith said Friday.

"We had a very close encounter.By close I mean it was it was within 30 or 40 feet to the helicopter, which could be significant, possibly catastrophic, if we had collided with the drone."

Griffith has been a pilot forAir-1 for two years. He said his encounter over downtown Edmonton at about 10 p.m. on July 8was the closest the police helicopter has ever come to colliding with an unmanned aerial vehicle.

If a collision had happened, Griffith said, the impact would havebeensimilar to hitting alarge bird. At the speed the helicopter was travelling at, itcould havebeen catastrophic.

"It would come through the windshield. It could incapacitate the pilot. The tactical officers are trained in the event that if the pilot is incapacitated they could land it, but it could significantly damage the aircraft," said Griffith.

Even if it didn't hit the windshield, it could have hit thetail rotor or been sucked into the engine, causing the helicopter to lose power in the air.

Both officers on boardAir-1 are trained to land the helicopter without power.But if they are flying over the city, it would leavethem in a dire situation, Griffith said.

"It could be fatal. More importantly it's the citizens of Edmonton that are below us. If there is a catastrophic failure, we have to come down somewhere."

Transport Canada says drones are not to be flown near moving vehicles, highways, bridges and busy streets, or anywhere the devices could interfere with first responders.

Drones are only to be flown in daylight hours and no higher than 90 metres (300 feet) above the ground.

In the incident detailed Friday, the drone was flying far higher than the legal maximum.

"At 1,500 feet we wouldn't be expecting a drone to be operating at the altitude," he said.

Griffithsaid the drone was flying so high, there's a good chancetheoperator wasn't able to see it, a legal requirement.

Police are investigating. If caught, the culprits could face charges under the Criminal Code and the Aeronautics Act.

"We will look for the users and we are quite successful at finding them," said Griffith.

About 30 minutes after the July 8 close call, two other smaller drones were observed in the same area, police said.
