ImageGear,
Don't know the guys but what odds that one was an Engineer and one was a beancounter ?
Pretty good odds
Mulally was an engineer, graduated from the University of Kansas with a Masters in Aeronautical & Astronautical Engineering and then was a Sloan Fellow at MIT. He went to work directly from there to Boeing. He lead the team at Boeing that designed the two-man common cockpit for the 757/767 aircraft and then moved on to the 777, first as Director of Engineering, then as VP and GM.
Stonecipher received a degree in physics from Tennessee Tech, went to work for Allison as a lab technician then went on to work at GE Aircraft Engines, working his way up to become VP of Commercial Engine Sales. He left GE and went to Sundstrand, then to McDonnell Douglas and then to Boeing. He was somewhat more of a bean-counter than an engineer.
