The Guardian (UK) got hold of the pilot's CV, see below. Looks like the passengers were very lucky to have Mr Sullenberger in the hot seat. The right stuff indeed.

Chesley Sullenberger, from Danville, California, is a 29-year veteran of US Airways with 40 years' aviation experience and about 20,000 flight hours in jets, propeller planes and gliders.
He flew F-4 jets in the US air force before beginning his civilian career, and now gives speeches on aviation safety. Among his interests are studying the psychology of how teams cope in an emergency,
Sullenberger is a graduate of the USAF academy, Purdue University and the University of Northern Colorado. He was a speaker on two panels at the High Reliability Organisations (HRO) international conference in Deauville, France, in 2007 and has just been named a visiting scholar at the University of California, Berkeley.
He served as an instructor and Airline Pilots Association safety chairman, accident investigator and national technical committee member, local media said. He has participated in several USAF and National Transportation Safety Board accident investigations.
His safety work led to the development of a Federal Aviation Administration advisory circular. Working with Nasa scientists, he co-authored a paper on error-inducing contexts in aviation. He was instrumental in the development and implementation of the crew resource management course used at his airline and has taught the course to hundreds of colleagues.
