Caught up in the airline security scare last month, JK Rowling won an argument with New York airport officials to allow her to fly with her latest Harry Potter manuscript.

Speaking on her website about being allowed on board with the manuscript, Rowling said: “I don’t know what I would have done if they hadn’t; sailed home, probably.”

She had been at a New York reading charity according to Associated Press, and was flying home at the height of security measures after British police intercepted an alleged terror plot to blow up airlines bound for the US.

“A large part of it is handwritten and there was no copy of anything I had done while in the US,” she said.

Eventually airline officials allowed Rowling to board with the manuscript “bound up in elastic bands.”

It’s book number seven - the final volume of the Harry Potter adventures - she is yet to come up with a title.®
