Apologies if this has appeared already.
At Shawbury in the eighties, the local hunt would occassionally encroach on the undershoot to the detriment of safety. The call from the local controller would be "XXX break off the approach, summer hunt crossing the undershoot." Well, the fickle finger of fate does not wait long to catch out the unaware and sure enough the fateful day came when the PAR controller readback the call as "XXX break off the approach, some c*** crossing the undershoot."
