Will be flying then so have set pvr to record (hopefully) so thanks for the heads up. I hope its a proper tribute to 617 squadron and not an excuse to see more Buffalo airways. Looks like this is a summary: http://http://www.history.ca/ontv/titledetails.aspx?titleid=261043
This was shown in the UK last year. Unless it has undergone a re-edit it is less driven and focused on Buffalo than you might think.
The main focus of the docu is a Cam professor constructing a scale mock up of the raid and discussing the challenges that had to be overcome. Personally I think the guy comes across as a bit of a prat and does not portray engineering in a good light, but that is just me...
