Probabilities
The probability of passing a hashpoint on a 50-graticule flight is 22.2%, not 25%; Sourcerer's maths were out. Explanation. Still pretty good, though, and I'm going to have to look at a couple of my recent long-distance flights to see if I can spot them! I've previously tried to take my GPSr on planes but it doesn't work reliably; I'd not thought of using a flight-tracking tool! --DanQ (talk)
