3 A cynic is someone who knows the price of everything and the value of nothing (Oscar Wilde) In any personal interaction you have a choice: You can invite the other person to live, or you can invite them to die. The choice is yours. (Glenn Taylor) There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact. (Mark Twain) [Thinking is] what a great many people think they are doing when they are merely rearranging their prejudices. (William James)

8 Harold S Johnston One of Johnston's most significant research efforts has been on the destruction of the ozone layer. This layer in the earth's upper atmosphere protects people from the Sun's ultra-violet rays. Chlorofluorocarbons (CFCs) gaseous compounds often used in aerosol cans, refrigerants, and air conditioning systems deplete this ozone layer, resulting in increased amounts of harmful radiation reaching the earth's surface. The Environmental Protection Agency has imposed production cutbacks on these harmful chemicals. Much like CFCs, nitrogen oxides also damage the ozone layer. During the late 1960s, the federal government financed the design and construction of two prototype supersonic transport (SST) aircraft. An intense political debate over whether the program should be expanded to construct five hundred SSTs was waged. Although Congress was split almost evenly, both houses voted to terminate the SST program in March, Johnston's articles and testimony suggesting the negative effects SSTs could produce on the atmosphere led two senators to introduce the Stratosphere Protection Act of 1971, which established a research program concerned with the stratosphere. The resulting 1971 program, with which Johnston was affiliated, was called the Climatic Impact Assessment Program (CIAP). Among other things, CIAP concluded that nitrogen oxides from stratospheric aircraft would further reduce ozone. CIAP recommended that aircraft engines be redesigned to reduced nitrogen oxide emissions.

The objective of the program was to discover if the detonation of an atomic bomb would ignite the atmosphere.
