A valuble lesson too - expect the unexpected and keep your head on a swivel...give you an example a few years back BRL and I were in an Arrow on very short final at Popham (en-route to a proone fly in as it happens) and this fella in a 152 cuts in across our bows

- bit of a hasty GA let me tell you!

Later investigation revealed that apparently this bloke was locally based and had a bit of a reputation as a queue jumper...
