How to determine if pilots in crashes flew again? I checked this post on Airliners.net , but the formatting is hard to read, and the information or hearsay may not be trustworthy. Also, I'm hoping for a more efficient, efficacious method, rather than researching each accident separately. 

I'd wanted to be advised if pilots, suspected of (provable, veritable) pilot error, were still flying: Qantas Flight 1, American Airlines Flight 1420

Yet I'd be heartened and inspired by heroic or esteemed pilots, like those for United Airlines Flight 232.
How can I determine if a driver who was involved in an automobile accident is still driving?
The answer is "They probably are."

Broadly, unless the pilot died or the FAA (or equivalent authority) revoked their license as a result of their actions there is no reason the pilot wouldn't still be flying unless they decide to hang up their wings for personal reasons.
They may not be flying for the same airline, and certainly will have had some sort of remedial training (particularly if they were involved in an incident where pilot error was the cause), but damaging an aircraft is usually not a career-killing move unless one makes a habit of it.



If you want to know for certain about a particular flight crew you would need to research each accident separately (locate the pilots' information - name or certificate number - and check something like the FAA airman records branch to see if the pilot still holds a valid certificate and medical.
