I remember arriving at work (one of the hangers that used to occupy the southside of MCR) one day after a 'bit of a hooley' to see the B747 that had been impounded for not paying it's bills seemed to have moved. Being the good little ops type that I (still) am, i phoned up the Ops Mgr and told him so. Yeah yeah yeah was the soryt of response, followed about three hours later by a 'thanks for that, sorry I was a bit rude' as said B747 had indeed been pushed back onto the grass by about 25 feet.
Mother nature, never ceases to amaze and humble.
