Here’s a less well covered area (I assume) - North Africa, 34 deg, 7 mins, 48.02 seconds North, 4 deg 39mins 53.53 seconds West
5,000 ft:
10,000 ft
15,000 ft
20,000 ft
25,000 ft
30,000 ft
35,000 ft
40,000 ft
45,000 ft
50,000 ft
So quality at 50,000ft definitely a bit less good, but not a material issue at to 30-35,000 ft level here either
