Distance Calculator

Hi! I've been using Flight Central Route Browser's distance calculator for a while. Till now i used to calculate distance/time for airports within United states and its accurate. But when I tried calculating distance/time for some international routes its giving inappropriate negative(minus) values.
Example- try New York(KJFK) - Mumbai,Ind(VABB) route, the distance should be 6777nm, 15hr 24mins but its showing -4038nm,65528 Hr 65478 Min .
Also its showing a straight line on the map thats not correct, in real situation we do fly on a great circle path.

Looks like it calculated the walking time...

Hadn't seen that problem before and will put it in the queue for fixing. Thanks for letting us know.

Looks like it is still having trouble with leg calcutations. SAEZ-ELLX shows -4679 nm. Great Circle Mapper show it 6112 nm: Great Circle Mapper A Great Circle Mapper intigration would be great.
