LOX is hardly available from the local Carrefour and is marvellously combustible. Amazing really that 2 of the most highly combustible gases on the planet (hydrogen and oxygen) form inert water when combined... But beware of LOX, mainly because it does not actually need an ignition source - as the following cautionary tale will tell you. Picture a steely-eyed fast jet pilot on a transit flight across the Atlantic driving one of Her Majesty's finest fighting single-seat machines. Halfway across, feeling hungry, he unwraps the ham sandwiches that have been carefully prepared by catering staff to sustain him on his trip. Lowering his oxygen mask from his mouth, but leaving it dangling from the straps in front of his face with the oxygen flow still on, the intrepid hero goes to take a bite of this culinary delight. At which point spontaneous combustion of the grease in the ham and butter occurs, which spreads to his moustache............. cue much hilarity from colleagues and, yes, this is a true story.
