For me it has to be the Vulcan.I well remember it coming over Weston Super Mare Airfield,on a low pass,and turning on full power for a steep climb.No wonder I now wear hearing aids, but that could also be through listening to Deep Purple !!!!.
Lets not forget the Concord,for sheer style.Its about time it was brought back.One severe accident,and it was taken out of the skies,what about all the disasters 747s etc,have had and they are still flying.Once again we led the World. The Yanks had nothing like it,so they just had to ban it frm their Airports.Now we are going to waste millions sending a probe toward the Sun . Why?? We all know its a big ball of flame thats very hot,and that it unlikely to have any living thing on it!!!
