Following in the footsteps of her successful BBC2 1998 series, "Coast to Coast", "As the Crow Flies" describes Janet Street-Porter's attempt to walk the 350 miles from Edinburgh Observatory to Greenwich Observatory - in a dead straight line. She discovers a new way of walking - the OS map isn't quite so handy when you can't stray off a line you've drawn on a map. What's more useful is a heavy clearing stick, the power of persuasion and the patience of a saint. Janet adopts the old ramblers' cause of the "right to roam", discovering some of the most beautiful countryside in Britain - as well as bargaining and begging her way into secure properties, dodging Boeing 737s on take-off, and invading army bases and Saturday morning golf tournaments, all in the name of completing this mammoth walk strictly as the crow flies. She also has plenty of amusing encounters along the way - not only with locals (including some irate farmers!), but also celebrity friends like Sting, Ewan McGregor, Vic Reeves and Elton John, showing her their local patches. "As the Crow Flies" is published as a companion to the seven-part BBC2 television series.
