Harry Curtis Stonecipher (born May 16, 1936) is an American business executive who was president and chief executive officer of American aerospace companies McDonnell Douglas and, later, The Boeing Company. Stonecipher was widely credited with the seeming resurgence of Boeing after government procurement scandals. However, his tenure also included major decisions to change Boeing's design and sourcing process for the new 787 airliner. These decisions later proved to be organizationally and financially disastrous for the company. Stonecipher was forced to resign from Boeing following the disclosure of an affair with a subordinate, in violation of the Boeing Code of Conduct.
