Note the wings on the breast of Stephen Harper's bomber jacket as he visits Slave Lake with Ed Stelmach. A badge with two wings is worn by a member of the Canadian Forces who has completed a course of training qualifying them as aircrew (non-aircrew like engine or airframe techs wear a half-wing badge). These full-winged trades include pilots, navigators, and loadmasters.
The courses are arduous and train the badger wearer to very high, world-class, degree of competency. The wings are not awarded until the courses have been successfully completed in the same way the title Doctor or the post-nominal PhD or MD are not used by people who have not earned the associated parchments.
Stephen Harper has not completed a course of training culminating in the awarding of such a badge, yet this is the second time we see media images of him in the same jacket. The first was several days ago during the Manitoba flooding. If you look closely, someone had the wherewithal to remove the wings from this particular garment before the PM donned it. Not so most recently, as we see above.
The last time I checked, misrepresenting your qualifications like that was a crime with jail-time. Moreover, it demeans the integrity of the institution and slights every aircrew member who has qualified for their wings or died wearing them.
I don't know what he's doing for the Air Force on those long flights that they let him keep the coat...but I can tell you that in the army I joined, a politician walking onto an installation wearing half a uniform and jump wings, or HMC Dockyard or Ship wearing submariner's dolphins, would likely need the medics to carry him out...
