Boeing CEO Dennis Muilenburg said Tuesday that the company will lower costs on the Air Force One replacement “simplying requirements” and using “commercial practices” after meeting with President-elect Trump.

“We talked about a couple of topics. We discussed Air Force One, we discussed fighter aircraft, we made some great progress on simplifying requirements for Air Force One, streamlining the process, streamlining certification by using commercial practices,” he said. “All of that is gonna provide a better airplane at a lower cost.”
