Here's some interesting code:

// Get the lattitude and longitude values
double latS = StrictMath.toRadians(aS.getLatitude());
double latD = StrictMath.toRadians(aD.getLatitude());
double lngDiff = StrictMath.toRadians(StrictMath.abs(aS.getLongitude() - aD.getLongitude()));

// Do the math - this makes my head hurt
double p1 = StrictMath.sin(latS) * StrictMath.sin(latD);
double p2 = StrictMath.cos(latS) * StrictMath.cos(latD) * StrictMath.cos(lngDiff);
double distD = StrictMath.toDegrees(StrictMath.acos(p1 + p2));

// Convert to miles
int distance = StrictMath.round(distD * 69.16);

Basically, given the latitude and longitude of any two places on the Earth in degrees, you can calculate the length of the Great Circle route between those two points. We know can calculate the length of the flights flown for all 38,000+ PIREPs. Check the statistics to see how many frequent flier miles you have!

Cheers!

Luke

Although that bit of code is a bit over my head, it is really interesting, and I can see the point.
