What path with the Jetliner, Buzzard ?  (For those not in the know, a 50s era medium-range jet developed by Avro.  Wanted by Howard Hughes at TWA and also NorthEast AL, but scuppered by the British government which refused to supply engines that were for the day efficient, forcing a redesign. AC also on the cusp of buying. Ultimately the Lib government scrapped the whole thing.) The Yanks had zero to do with the Jetliner's demise.  We had 100%.
