33+ years at the same major aerospace and defense company. ME, test & systems engineering involved in space, commercial aircraft and fighter aircraft R&D and test programs. Seen many one of a kind systems and hardware (most successful, a few not) which always made it interesting and challenging - the main reason for staying at one company so long. Plus I like working with new people involved in the various programs, probably met and worked at various levels with 100s of people over the years. Some of the programs had 300-400 people working on them - lots of skilled and awesome people.
