The satellite was headed to geostationary orbit over africa, 4Deg west. Unless you live in northern africa the satellite would never be overhead.

Being pedantic: In GEO, with an orbital radius of about 42Mm, and earth having a radius of 7Mm, that gives a radius of 7Mm * acos( 7Mm / 42Mm ) ~ 9800km around 4°W (almost a hemisphere), for which it would be overhead.

But admittedly it would only give service to a portion of that.

Props for Mm, instead of 'thousand km'.
