The first time I went to BPB, we flew there and back (it was the cheapest way to get from London to Blackpool). This was just after they started insisting on X-raying everyone's shoes before you even got to the main security check. A very hastily added extra that caused no end of tailbacks even in a tiny airport like Blackpool. Returning home that evening, I slapped a sodden, ruined pair of trainers down on the tray for the scanner with a "SPLOT", sending water splashing everywhere. The Stazi agent looked at me, and asked in a matter-of-fact voice, "... Valhalla?"
