While I think it might be feasible to drop a tank and have it appear to drop down from the a/c, and out of sight (and then quickly de-selected), I think trying to achieve any sort of realistic trajectory would be pushing it a bit. You've got to remember that the animation origins are relative to the a/c so after dropping something, you'd have to bare in mind that the a/c, and therefore the anim orign, are moving. If the a/c turns after dropping the tank it would be very difficult to keep the tank moving in a straight line with the available anim controls. The same thing applies to climbs or descents, but this would be less apparent from the a/c views. Would look a bit odd from the tower though:) LeeE _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
