James Bond unfolds the plane's wings, takes off in the micro jet, and is soon fired upon by a particularly tenacious surface-to-air missile. The ever-clever secret agent turns the missile against his foes by flying the tiny plane through the hangar where he had originally been caught and causing the missile to detonate against the very aircraft he was sent to sabotage.
This opening sequence was a skillful mixture of the aircraft in flight and special effects. The credits of the film state that the aircraft is called the Acrostar that was built and piloted by John William "Corkey" Fornof. However, that is only part of the story behind this remarkable craft. The Acrostar is actually a kit plane designed by engineer Jim Bede and known as the Bede BD-5J. Some number of these kits were assembled to a modified design by Corkey Fornof along with fellow BD-5J enthusiast and stunt pilot Bob Bishop. These two pilots formed their own aerial acrobatic team called the Acrojets, and only their modified BD-5J models are actually referred to as the Acrostar (or Acro Star) Special. One of these Acrostars was filmed for "Octopussy" while being flown by both Fornof and another stunt pilot named Rick Holley.
