It occurred to me in a bored moment while I was waiting to be shuffled to the terminal building at Heathrow the other day that I did not know how long it takes to wash an aeroplane the size of a 747. In fact does it even need washing on the outside at all given it flies through clouds and do clouds clean it off as it flies around the world? Could this be the silver lining on the acid raincloud? If it does need a wash, does a plane wash look like a big car wash or do they use a jet wash to get the deed done?
