747-8

Commercial aerospace is a long run business. The gestation of new programs takes years.   Of late, add a few more years to the newer and vastly more complex aircraft programs.

In studying the following chart, note how Boeing has started to simplify its commercial business.  It may have a number of airplanes in its sales brochures.  But there are three that matter; 777, 787 and of course 737. Continue reading

Mr Joe Sutter was 93 when we made this brief video with him. Lufthansa awarded him their first lifetime achievement award.  As you see him here, he recently had heart surgery.  What an impressive man.  After this interview he sat on a stage and took questions for about 45 minutes from an audience.
