BAE 146-100 G-SSSH at Hatfield in Septmeber 1981. This was after roll out and before the first flight, whilst they did some photo shoots on the runway. Hatfield was never a busy place at this time and using the sole runway didn't seem to cause any traffic issues. Note they had painted the tug in same colour scheme for the event.The tug drivers found it hard work and are taking a break, putting their feet up!
