Maybe one has to be English to understand that article. Just how does moving the aircraft's location mitigate the risk of flying into a crane in fog?
Errm....is this a trick question?
Operate from an area where there aren't a load of high-rises, cranes and people and you lengthen the odds of hitting any of them
Now, If you
really meant to refer to the change to Military Pilots only.......Well, the cranes would bow to H.M. as her Chopper hove into range, thus clearing the way.
