AVIATION: Area of Agreement

General Motors Corp., long harassed by controversy over its Allison aircraft engine, last week distributed a booklet packaged in heavy cellophane, and titled: Airplane Power (with special reference to engines and altitudes). With the booklet was a note from G.M.’s genial Customer Research Director Henry Weaver: “After a long series of controversial sessions with our different engineering groups, aviation experts and military censors, we finally decided … to omit everything on which the experts are not in full and complete agreement. The enclosed is the result. .. .”

The enclosed booklet consisted of a handsome cover picturing four Allison-powered planes (Lightning, Airacobra, Tomahawk, Mustang), a noncommittal introduction and conclusion, and 40 blank pages.
