I wonder how much you can carry? My guess is that the Chunnel is secured to more-or-less a commercial aircraft standard. If that's the case, even water would need to be purchased/filled on the secure side. No multitools either (agh!).

Anybody have direct info about this?

[P.S., I'm just tacking onto the tail end of the thread. Mods, can we create a universal codeword/acronym for this?]
