(See my follow-up several hours before yours.)
However, according to my calculations, it exceeds the latter.
The equatorial rotational speed of Terra is ca. v_eq = 1040.3955 mph
(Cox, 2000). The latitude L of Oslo, Norway, is ca. 59.95° N (GeoHack).
The rotational speed v_lat of Terra at latitude L is approximately
v_lat = cos(L) × v_eq
= cos(59.95°) × 1040.3955 mph
≈ 520.98 mph.
So your airplane travels 29.02 mph faster than the Earth rotates at that
latitude.
