It’s UPT, not UBT. My gut feeling tells me no aviation bomb is EVER going through UPT. 😀 My son went through it. The next phase was RTU, though my son told me they changed the name, but they still do the same thing. My son knew what he would be flying, before he went to OTS at Maxwell. His RTU (or whatever they call it) was at Holloman. When these guys finish UPT, the Air Force doesn’t point them to their assigned Aircraft, and say, go fly it. They work them into it. After Holloman, he got about 4 more months of flight training at Indian Springs. He makes Captain next month.
