    X-15: Typed Letter Signed to Neil Armstrong from A. J. Bailey at Honeywell Regarding the Simulator Development, Directly From The Armstrong Family Collection™, Certified and Encapsulated by Collectibles Authentication Guaranty. Two 8.5" x 11" pages on Minneapolis-Honeywell Regulator Company Aeronautical Division, May 17, 1960. Bailey was Chief Engineering Pilot on this project and worked closely with Armstrong on many aspects. Interesting content, in full below.

    "The day after you finished up here at Honeywell I went out to L. A. to have a look at the X-15 simulator. This was rather a rush deal because we were only scheduled to spend one more day on the simulator. However, even though I had only a few hours to look at the system, I think my trip was well worthwhile. I noted a number of things that should be clanged to improve he general handling qualities for better pilot acceptance.

    "We will be back on the simulator sometime in July with all the improvements incorporated. At that time I will contact you to see if you can spend a day in L. A. with me giving the system a good evaluation. I'm convinced the simulation, although deficient in some respects, is good and can provide us with valuable information if correctly used. Also, I feel that pilot recommendations should have a larger part deciding or influencing: breakout forces, force gradients, control harmony, function selector design, etc. Unfortunately I have been so closely tied to the flight testing of the system that a lot of these other areas have been neglected.

    "If you have a few minutes to spare, perhaps you could advise me where I can find some of the following information.
    1) I would like to find out a little about the pressure suit being worn in the X-15. That degree of mobility does the pilot have when pressurized. His hand and arm mobility and finger dexterity should be considered when arriving at breakout forces, positioning of function selector switches, etc.
    2) What can you tell me of any studies made at Navy Johnsville regarding pilot control under g conditions.

    "I think this gives you a good idea the type of information I'm trying to gather.

    "Last night I developed the film that I took while you and Joe were here. Tonight I'll dust off my enlarger and see if I can turn out a few quality pictures. Enclosed is a newspaper clipping about Joe - front page stuff. Forward it to Joe for comment."

    Original folds, fine overall. Each sealed in a numbered archival sleeve. This lot will include Statements of Provenance signed by Neil Armstrong's sons, Rick and Mark.

    This was my first time dealing with an auction house, and I am 100% completely impressed with Heritage. There is not an aspect of this process that I have a critique for.
