As to Bridges, the two over the Menai Strait (Telford's lovely old suspension road bridge) and the old box railway bridge (burned out after my time) absolutely begged to be flown under with our Spits and Vampires. But the certainty of detection (and subsequent sacking) kept our youthful ardour in check.
One occasion when flying under a bridge did go disasterously wrong is recounted in my post here:
