Don't walk under the wing - why not?
When getting off via the back door of an aircraft in the UK, there's always an announcement asking pax not to walk under the wing on the way to the terminal, and usually barriers, or a person standing under the wingtip to stop people from doing so.
Why is this? Presumably there's some H&S issue, but what is the actual risk here? I noticed at the weekend that nobody seemed remotely bothered where I walked in Dublin, only in the UK.
