Western Union Telegram from Tom Hayes to Hubert Mitchell.

The telegram discusses the park project development and has a note on the back, presumably written by Mitchell, listing what he needs to discuss with Hayes over a telephone call.

"Dodgem Your Next Ride" advertisement.

This card has an image of the "beautiful Fibreglas Space Age Dodgem car" and a price for it.

"Film of Apollo 11 launch. LBJ, Spiro Agnew, Johnny Carson, Hugh O'Brian, Barry Goldwater, Lady Bird Johnson, Hermann Oberth..."

This film shows the "VIP" section of seating for the Apollo 11 launch. The film shows them going to the stands and then watching the rocket as it takes off. Included are many contemporary celebrities, such as Lyndon B. Johnson, Spiro Agnew, Johnny Carson, Hugh O'Brian, Barry Goldwater, Lady Bird Johnson, and Hermann Oberth.

"General Formulation of the Iterative Guidance Mode."

From the abstract: "This report discusses the iterative guidance mode and its application to three-dimensional upper stage vacuum flight. It is an inertial or closed system mode in that the only inputs required after liftoff are available from the onboard navigation system. That is, the iterative scheme computes steering commands as a function of the state and of the vehicle - velocity, position, longitudinal acceleration, and gravitational acceleration - and the desired cutoff conditions. The guidance commands are updated each guidance cycle, using the updated state of the vehicle. The iterative guidance scheme is a path adaptive guidance scheme in that it will retain its optimization properties under all expected types and magnitudes of vehicle perturbations without any loss in accuracy at liftoff."

Draft of "Concepts of the Iterative Guidance Law for Saturn Launch Vehicles."

The summary notes, "In 1960, research work was begun to develop new guidance concepts for the Saturn space vehicles. [...] This paper presents the basics of the Iterative Guidance Law developed for Saturn launch vehicles to meet these new requirements of space age guidance. The development of the Iterative Guidance Law and the results and ideas presented in this paper are due primarily to Mr. Helmut J. Horn and his associates in the Dynamics Analysis and Flight Mechanics Division of the Aero-Astrodynamics Laboratory." Marked "Research Review, OK" in the upper right corner of the first page. The document includes corrections and additions to the text in red pencil.

Summary of the Iterative Guidance Mode.

"A Comparison of an MIT Explicit Guidance Principle with MSFC Iterative Guidance."

From the summary: "Both [guidance] schemes steer toward a specified end point. The MIT scheme uses thrust to cancel out the effective gravity, a nonlinear term, which may be inefficient in certain cases. The MSFC scheme is more closely connected with calculus of variations and optimization theory in a reasonable degree of approximation."
