Sometimes its great to just disappear for a while; I think. I work at an airline now and we fix planes all day long. its actually quite interesting really and you never quite figure how large an aircraft is until the day you are seated in the aircrafts belly and you dont cover much space then it hits you that its a bloody big invention. But hey thats just me; thats what happens when a bit of grease starts to leak into your head...too much thinking
