Here’s what would happen next if a jet airliner went down outside Dettah.

This week, Canadian Joint Operations Command is running a training exercise in the NWT which dummies up a major air disaster.

The exercise allows members of the Armed Forces to practice how they’ll deal with everything from injured passengers to securing the area.

Watch scenes from the exercise at a gravel pit outside Dettah on Tuesday, and hear from Master Warrant Officer Darryl Cattell as he explains what’s happening.
