BUG Flight Mode not resetting to "Watching"

[hotzenklotz]

Problem Description

If switching from flight mode (while recording status = True) to orthogonal mode, moving view port some distance away from original point and coming back to flight mode (while recording status still True) nodes are created automatically.

Way to reproduce

1. Set some nodes in flight mode. (Recording = True)
2. Switch to orthogonal mode.
3. Move viewport some nanometers away from original point.
4. Switch back to orthogonal mode. --> a new node appears in the middle of view port.
   If this procedure is done while flight mode is in watching mode (not recording), then no new nodes are created.
