SECRETARY’S REPORT 143 
REPAIR, PRESERVATION, AND RESTORATION 
A small office has been provided at the Suitland storage facility, and 
a paint and spray booth is under construction. A fabric department 
and document room are in process of planning. Additional machine 
tools and equipment have been acquired. Most of the aircraft and en- 
gines in the Aircraft Building have been moved to Suitland and are 
undergoing cleaning, repair, and preparation for storage or exhibition. 
In anticipation of the restoration program which lies ahead in 
preparation for the new building, the Director has visited many air- 
craft factories and has received assurances of cooperation from the 
manufacturers by way of providing us with technical data, lending 
mechanics to assist in restoration and to advise on methods of display. 
ASSISTANCE TO GOVERNMENT DEPARTMENTS 
The National Air Museum has served many Government depart- 
ments during the year. Among these were the Department of Justice 
in connection with patent litigation, the Voice of America, the De- 
partment of the Air Force, and the Department of the Navy. 
PUBLIC INFORMATION SERVICES 
Providing information to the public continues as a very active and 
growing function of the Museum. For example, telephone calls dur- 
ing the year requesting historical, technical, or biographical informa- 
tion on the development of aviation numbered more than 700 from 
Government agencies and more than 1,400 from other sources. Corre- 
spondence is averaging around 100 letters a week. Approximately 
19,000 leaflets were distributed during the year, in addition to some 
1,100 photographs and drawings. 
The Museum continues to serve aircraft manufacturers, airlines, 
publishers, authors, schools and colleges, and many individual stu- 
dents, teachers, and research workers. 
REFERENCE MATERIAL AND ACKNOWLEDGMENTS 
Many useful and valuable additions to the reference files, photo- 
graphic files, and library of the Museum were received during the 
year. These records and documents are helpful to the Museum staff 
in providing information service, authenticating data, and for 
research.

providing this material is sincerely appreciated :
