The letter is from A.S. Mike Monroney of the United States Senate, responding to a complaint made by Mr. Roy G. Garrett regarding the negative impact of sonic booms on his home improvement business. Monroney assures Garrett that the Federal Aviation Agency will be informed of his concerns and that they will address any damage claims promptly. The letter also discusses the importance of conducting tests in Oklahoma City for the development of aviation industries and the need to gather information on the effects of supersonic flight. Monroney includes a pamphlet on the controversial program for Garrett's information.
