Four Vulcans XM657, XL427, XM575 and XM648 are about to scramble at the last airshow where Vulcans were present in great numbers. It is a pity that it was impossible to save the sound as it is only in my memory that I feel the ground shake. Despite the magnificence of the last, now grounded Vulcan, G-VLCN, it was much lighter than these with the engines understandably downrated to preserve their life.
