Possibly this:

### Great Circle distances
### Use different sign to N and S, and to E and W
### (does not matter which sign)
### Lat and long must be in degrees + decimals (sorry)
"globedis" <-

    function(lat0, lon0, lat1, lon1, km = TRUE) {

    phi0 <- pi/180*lat0
    phi1 <- pi/180*lat1
    lambda <- pi/180*(lon0 - lon1)
    delta <- sin(phi0) * sin(phi1) + cos(phi0) * cos(phi1) * cos(lambda)     delta <- acos(delta)
    dist <- 60*180/pi*delta
    dist <- dist %% 10800
    if (km)

        dist <- 1.852 * dist
    dist
}

Which says that Boston is nearest to my office (6100km). The other alternatives are Baltimore 6720km, Chicago 6800km, Raleigh 7050km and San Francisco 8240km.

In more practical metric of flight time, Baltimore is closest (OUL - BWI 12h55min), but Boston and Chicago are not much further away (OUL - BOS 14h00min, OUL-CHI 14h15min).
