Default Seaplane Resurgence?

The spaceplane continues to
fly until it reaches its escape velocity of around 966 km/h.

..Flying machines don't have an escape velocity. Planets or
stars have one, but not aircraft. We are talking about escaping
_something_, but what? what does the number relate to? For the earth
escape velocity is 7 miles per second, or a bit more than 40 000
km/h.
