One of the many curiosities is that while we have (and must have) an RT license, many ground vehicles seem to be operated by people who have simply been told where the transmit switch is. These same personnel have access to aircraft movement areas, and active runways. If the level of training applied to communications is similar to other operations, exactly how well trained and disciplined are these?
Operating at Glasgow, it is interesting to note the number of people who simply pay lip service to any form of ramp discipline, whether in vehicles or otherwise.
Moving away from UK airports, you see some really interesting events, including being cut up by a vehicle while taxying out (BCN), Being chased along the taxyway by dogs (egypt someplace), aircraft towed at ridiculous speeds (PRG), ops vehicles asked to confirm and read back a clearance such as entering an active runway (back the UK).
I wonder how many near misses occur simply because operating crews did keep a bloody good look out and listen, and caught a problem before it became an incident.
