Harry Potter and the Transportation Security Administration

TSA officials on New York nearly prohibited JK Rowling from carrying the handwritten manuscript for the final Harry Potter book onto her flight to London. From her page:

The heightened security restrictions on the airlines in August made the journey back from New York interesting, as I refused to be parted from the manuscript of book seven (a large part of it is handwritten, and there was no copy of anything I had done while in the US). They let me take it on, thankfully, bound up in elastic bands. I don't know what I would have done if they hadn't; sailed home, probably.

Curse these muggle transit regulations!
