On the Bruntingthorpe Aviation site they state that XR808 is "holder of the Blue Ribband for the fastest crossing of the Atlantic by a sub-sonic aircraft." We've been trying to confirm this but are unable to find more about this record. Anyone with more info about the above records or XR808's achievement?
