This is very true - for example, his VP Propulsion Development, Tom Mueller, spent 14 years as a rocket product manager at TRW, and spent 6 years leading a team of 80 engineers developing a candidate engine for the Delta IV, and winning plaudits like a chairman's award for technical excellence but without anything he worked on actually getting launched. I can't imagine how gratifying it must feel for him now to watch things he made flying into orbit and opening access to space. It's hard to beat that kind of real accomplishment as a job perk.
