So, I just got a look at the bonus agreement...
If you leave (fired) at/before the 1 year you pay back all of it ($5k + 26IOE and $8k type if you qualified)
If you leave (fired) before end of 13th month you pay back all (all above plus the $10k at yr 1).
If you leave prior to end of 24 months they want you to repay roughly $3400 for each month shy of 24 (plus some if you got the type rating bonus).
