Filling out an ESTA form (Electronic System for Travel Authorization) is obligatory if you wish to visit the US. The Department of Homeland Security decrees so. Booking a city break in New York involved providing my details on the online Esta form. Bemused, as well as somewhat wryly amused, to be asked if I was planning to commit terrorist acts while in the US, I accepted it as part of the deal.
However, the thought then arose: I'm one of the "internet terrorists" that Tom Hicks referred to recently. Does this mean I'm on a no-fly list?
