Letter of Transmittal

To the Congress of the United States:
In compliance with the provisions of the Act of March 3, 19I15, as
amended, which established the National Advisory (C'onmittee for
Aeronautics, I transmit, herewith the Forty-fourth and Final A l nIal:
Report of the Committee for the Fiscal Year 1958. This report
covers the activities of the ('ommittee through the close of business
September 3(0. 1958, when it was superseded by the National Aero-
nautics and Space Administration.
The National Advisory (Conmmittee for Aeronautics is to be co m-
mended for its many contributions to the progress of aeronautical
science in the United States and for the spirit of teamwork in aero-
nautics it has inspired among leaders in science, the military and
industry. I wish also to acknowledge at this time the excellent work
and dedication of the Conmmittee's research staff who, over the years,
have given unstintingly of their talents in a manner which reflects
credit upon them and all other civil service persollel of the llnifted
States.

retaining sufficient solid area to guide the air uniformly past the model. Two other test sections operate at speeds up
