Memorandum by the Assistant Chief of the Aviation Division (Lister)

During discussions with Miss Dane of ATC and Captain Harrington of AAF I am informed that:

ATC no longer maintains command control of any air bases in Central or South America but merely occupies some of them on a tenant basis.
AAF maintains command control at two groups of air bases; namely, those under the joint Brazilian program and the 99 year lease bases.

Captain Harrington states that inquiries concerning lists of military air bases in the Western Hemisphere available for use by civil aircraft should be directed in the first instance to ATC, primarily because the list changes rapidly from day to day and the most current information with respect to the status of these bases is maintained by ATC.
