Had to find the kit for a Boeing 747 and a high school student to put the airplane together. A 747 out fitted with a large telescope would fly at high altitudes a door will open once the plane reaches a height. The telescope would then observe the cosmos. Not sure what happened with this project but, this was the model that showed the airplane and it’s hanger shown as a cut away.
