We used to play with it at school pushing it around on the desk!
On the Chinooks on air tests we needed an accurate reading of the outside temp at various altitudes when carrying out adjustments, this was done by calling up and getting the figures from the Odi station met office. After one flight the figures varied wildly, so the staish met man was asked where his figures came from and it turned out it was from wherever a weather balloon had been launched, in this case it was Liverpool!
As that was no good, a pole with a thermometer strapped to it was devised to take an outside temp reading... all went swimmingly until they dropped it in the cab smashing the thermometer, the floor and structure all had to be pulled out and cleaned to remove it all, it was down for a considerable amount of time and it was a brand new Chinook.
