Debunking...
Assuming mid Africa to eastern Greenland subtends 70 degrees of arc, with an Earth radius of 3963 miles, you're talking about 1.22 rad. 1.22 * 3963 = 4841 miles of Earth's surface is visible from the bottom of the pic to the horizon.
CONSERVATIVELY erring (for the sake of simplicity) that mid Africa to Greenland takes 70 degrees of the FOV, and that the shuttle is directly over mid Africa, the shuttle would have to be about 4000 miles up to get that much of Earth visible.
