National also came up with
this retractable gear
4 foot high retractable skid gear National designed and flew for use with the circlevision camera system developed by Disney. This is the film you see at Disneyland that in which you are surrounded by the image. The need for the retractable gear was due to the fact that the original camera system was mounted to the cargo hook and was jettisonable. That precluded us from flying over populated areas, these gear would retract out of the way of the lenses, and would allow us to land anywhere in case of an emergency.
