    To the Kind Attention of M. David Pike,

    Dear David,

    As I cannot fully confirm the London Longitude you actually used since the image is a bit blurred, would you be so kind as to indicate "your" London and NY coordinates used in your exercise ?

    Well, while you are at it, please also be so kind as to confirm your own end results, both on a spherical Earth and on an ellipsoidal Earth.

    As you seem to be using THE Datum ***** it will enable me to compare your results with own results obtained through both Vincenty's as well as Euler's + 3D  Methods.

    Thanks in advance, with my Very Best Ellipsoidal Navigation Regards :-) 

    Antoine
