This 217-page Project Blue Book desk file on the 24 April 1964 Socorro, New Mexico sighting by policeman Lonnie Zamora comes from the Rob Mercer collection. It contains the Blue Book record card, which carries the case as unidentified pending more data, along with Foreign Technology Division messages and resumes and a narrative of the sighting. It also holds inquiries about lunar modules, helicopters and VTOL craft, soil and radiation findings, and a letter by J. Allen Hynek rejecting Donald Menzel's hoax hypothesis.

I I I I I I I I I I I NWL .... PNEUMODYNAMICS CORP. NATIONAL WATER LIFT DIVISION SURVEYOR LANDING GEAR Project Surveyor is a _scientific task with the end requirement of successfully accomplishing a landing on the moon. ·The lunar vehicle lands on three legs. A shock absorber is incor- porated in each leg to dissipate some of the touchdown energy and to store the balance. NWL is responsible for the design, production, and testing of these shock absorbers, Model 1859. The design parameters are very severe. Temperatures range from+ 27 5° F to - 300° F, pressures inside the unit ~o up to 15,000 psi, and pressures outside the unit drop to 10- 4 torr. The required damping profile is both a function of unit velocity and unit stroke position. The unit contains a gas charge at 1500 psi and will retain such ·a charge for 12 months. External moving parts are encapsulated by flexible metal bellows. The unit uses a special grade of titanium (13 Cr 11 V 3 Al) heat treated to 185, 000 psi minimum. A very detailed and comprehensive reliability program controls this project. By the natu.re of its' end usage, the production of the shock absorber will be small. However, the engineering, product know-how, and special experience requirement are very large. This unit typifies NWL Company's capacity for small production runs on sophisticated hardware.Rob Mercer
