I was on the Caledonian B707 in the background. We were operating flights for Air Canada during a strike. I'd picked the aircraft up in Hannover (HAJ) and we ferried into Saskatoon (YXE) empty for a crew minimum rest. I was there to handle the check-in, however the Air Canada check-in staff were back at work and all I needed to do was the loadsheet before we left for Winnipeg (YWG - fuel stop) and Glasgow - Prestwick (PIK).
