+// Fixed a problem with the initial starting altitude.  "v->abs_view_pos" wasn't
+// being calculated correctly at the beginning causing the first terrain
+// intersection to fail, returning a ground altitude of zero, causing the plane
+// to free fall for one frame, until the ground altitude was corrected, but now
+// being under the ground we got a big bounce and the plane always ended up
+// upside down.

 // Revision 1.34  1998/12/05 15:54:22  curt
 // Renamed class fgFLIGHT to class FGState as per request by JSB.
