TLS, one page, 8 x 10.5, NASA letterhead, March 20, 1973. Letter to Anthony Polidoro, in part: "I work in the Airborne Science Office and in the Applications Aircraft Support Program Office here at Ames. Both offices are dedicated to utilizing aircraft as platforms for remote sensing of the earth and the atmosphere. Hopefully, with the information gained in the airborne program, we can help solve the pollution and resources problems of the earth…I am still available for space flight, and if the time comes when they need me back in Houston, I will certainly be happy to go." In very good to fine condition, with speckled small stains along the left edge.
