We had a couple of guys go home and make it back successfully when I went through. I tend to agree with the guys who say stay there in CMH. It's just too good of a job to risk losing by not making it back in time.
There's a lot to do nearby. I'd head over to Wright-Pat on Sat, then sleep in Sunday. You'll have to be in the pool early Monday anyway.
It sucks being away from home that long, but the upside is you'll be home about a week before you go to Flight Safety. Congrats on being in indoc!
If you DO leave, class should be out by 5, but you're probably playing fireman that day and it could run later. I wouldn't take the chance.
