I just got back from Brooks earlier this week for the FC1/MFS. I was fortunate to be in group one, which finished on the second day of testing and was able to blow off some steam that night in San Antone.
First day: dental/ekg/7 vials of blood/ depth perception/ UA/ maybe some color vision?/corneal topo/lunch/ 4 hours of BS psych testing - "do you still beat your mother?"
Second day - Drug UA/ additional battery of color vision tests / meet flight doc/ dialate eyes/ all sorts of eye crap/ don't remember.
Lots of sit and wait, but it's a good process. They have their #### together down there for sure.
Best of luck, feel free to ask me any questions. The lunch is awesome. 5 bucks and you get a turkey sandwich, chips, apple, cobbler, water - next day it's pizza!!! half a pizza for everyone!!
