Hummmm ... That's interesting. I was under the impression that it was
part of the fgfs CVS. Its apparently a case of the right hand not knowing
what the left hand was doing, i.e. I don't know how we got it.
I don't like hacks, but I will tell you I sure like flying from the tower
view. As you know it works w/ the 'v' key toggling from cockpit, to
external view, to tower view. When I get to the tower I can zoom in w/ 'x'
to get a better view of the aircraft.
Though I am a glider pilot, I also fly R/C models and the tower view suits
me best. A few of the UIUC (Roskam) aircraft models have bad yaw damping
and/or a dutch roll, and with those I get sick flying from the cockpit.
I sure hope something like this tower view gets to be permanent.
