There are a few negative comments floating around on Aurigny's facebook page following the late running and cancellation of Gatwick flights yesterday due to a passenger's illness. He required oxygen resulting in the need to replace an oxygen bottle on the Embraer before it could take off. One was shipped in from Guernsey on an ATR, which was itself delayed due to the required paperwork for carrying the bottle (dangerous cargo). Various people are asking why Aurigny weren't better prepared for such a basic situation and also why there wasn't a supply of oxygen bottles in Gatwick. Any thoughts on the operational aspects of this situation?
