I wouldn't do it. Fly for fun on the side. You would be giving up a great job, with great benefits, a generous pension, etc. You can transfer to different facilities for a change of pace. You can also apply for other ATO (non-2152) positions within the Agency. Don't give up just yet! If you leave, you would be giving up ALOT that you worked hard for.
Stay until you reach the minimum retirement age (57) so you can get the 1.7% FERS. Then go do whatever you heart's content!
