I'm flying your most recent route next month(ba218). If I see you I'm going to say something weird, like "I know where you've been flying James". I hope that's okay.
Regarding ideas, I noticed that you use great circle distance in some of your measurements, what about getting the actual flight data, and the graph showing deviation of your flight from the ideal.
Haha, if there is another James flying the plane, they might be spooked! I'm not flying to Denver for until at least August based on my current roster.
It would be great to use the actual distances (and would help me lap the moon a few more times), but there is no easy way to get the data. Our company flight plans which contain the actual route are in PDF format and with no easy API, and EuroControl (who hold the filed flight plans) charge quite a bit to have access I believe. I supposed I could screenshot the route and upload it to my server and have it OCR the route!
