I don't know Wg Cdr Cannard, but I have been deeply involved in several multi-engine fatal accidents.
I know that the Sqn Execs have one hell of a job on their hands with the families, not to mention the effects officers [or whatever they are called these days]. It is an incredibly stressful time. The OC in particular has not only to deal with the families [and their close relatives, which can be a terrible time], but they have to deal with the guys on the Sqn, keeping them going despite the loss of close friends and colleagues.
After 2 weeks on the Sqn, Wg Cdr Cannard had to deal with it all, compounded by the fact that he probably did not know some of the crew or their families.
In my view, the award was thoroughly deserved. The families would probably agree, given the chance away from the media frenzy...
