If you were the Captain on that flight you've gotta own it.....Flying or not, it was your bird. I would imagine being fired from a 121 Carrier for bending metal on landing is a pretty large obstacle to overcome QUICKLY.....you need a stretch of active flying now without anything happening before majors will be able to look past the incident in question. Put yourself in their shoes....nothing but risk and downside to hiring a guy previously terminated for bending a plane. Get a job flying something and start generating a squeaky-clean record.
