I'm slightly confused: how did the NZ Air Force put cargo on a passenger flight leaving from Vancouver???
Me too. Possibly NZAF got some replacement O2 generators from Boeing (near YVR) and shipped them by air? The legal alternative would have them going by surface transport, which might take weeks? I don't have a ton of DG experience, but I don't think you can get an exemption to carry those by air. I'll have to take a look at my DG manual later today.
