14th birthday and the second ever flight.
Sat in the back of a Chipmunk and looking "up" at a ship in the Bristol channel. Minutes later flying by the side of the same ship and being amazed at how big it was when viewed from sea level. After that the earth revolved a bit before landing back at RAF St Athan.
Its taken me a very long time from those days to get my PPL but the memory has never died.
