Pan Am Plan Would Drop Top Managers: The three top executives of Pan American World Airways would step down under a plan to be presented today to the judge overseeing Pan Am’s bankruptcy, a spokesman for the airline said, but there was no comment on a Miami Herald newspaper report that Randall Malin, USAir executive vice president of marketing, would likely get the job of running the smaller, reorganized Pan Am. Thomas G. Plaskett, Pan Am’s chairman and chief executive, Richard H. Francis, chief financial officer, and Peter T. McHugh, chief operating officer, would resign under the reorganization plan.
