Hansard, worry not. These fine blokes are happy to be in a piston powered aeroplane, and to meet old friends at an airfield. Do not be surprised if you find that the bomber chaps are a little taciturn. Their fearful experiences are discussed amongst themselves. Fighter guys tend to be more loquacious. In any event, it is a great privilege to spend a day amongst these men, and it is one of the very best things that you can do with a PPL .
