Right in line with Airshow's private use of a RCAF Cormorant search and rescue helicopter for his fishing trip, Harper turns out to be one of the few international leaders exclusively using publicly owned aircraft for travel.
The British Prime Minister, surely someone with much more serious security concerns than Harper, is using commercial flights to fly internationally. Indeed, according the CBC, so do the heads of many governments and countries.
Given that the air staff were completely willing to re-task a key SAR asset to pick up the defence minister on holiday, I might suggest that they change their name to Royal Conservative Air Force. You know, just to formalise their new job as purveyors of fine charter aircraft to the Conservative cabinet.
Oh the suck-ulence. Helicopter to plane, Salmon to Airshow to Lobster MacKay. He really is a Domestic Man of Mystery.
