As it happens..........
In 1974 I did my solo cross-country at Shoreham in a Beagle Pup 150 (precursor of the Bulldog).
As is always the case the aircraft was late back from the previous sortie, which was dual instruction.
Instructor climbed out, said "Off you go, no need to pre-flight, the check A's already been done."
So in I climbed and flew to Sarfend. Shut down and noticed a shiny mark on the prop. Inspection showed a thumbnail sized ding in the leading edge so I found an engineer who dressed it out and pronounced it safe. Continued to Lydd and then to Shoreham.
While in the circuit to land someone else called to say they had found some debris on the taxiway. You can gues what it was
