Nennt man fliegen fahren im himmel?

Basically no:

Flying —> In the air

Driving -> Typically on a surface

But there are some official terms of it:

1. Airdrivebeer
2. SpaceTravel
3. Balloondrive

But it also makes context-related sense:

Example: We drive on holiday

Declaration: Here driving is mentioned due to the speech type but it is actually meant to fly because the biggest way is covered by the aircraft in this example.

Example 2:

The balloons are called to drive because the pilot only maintains control and takes place less active than other flying objects. Due to the more or less passive control, in this example “travel” is actually correct!
