What aircraft?
If f-16s do not have radar that can acquire a hostile aircraft, then that means that they are vectored to the target.
So assuming a very dark night or IFR from 400 ft. to 12,000 or so, which certainly is not uncommon, how do F16s get visual contact?
Having spent more than a few rough nights on instruments, I can't imagine a radar vector to wingtip to wingtip on such a night.
In past years, I never had the time or the interest in military aviation to ask, but this accident intrigues me because I spent so much time in that area.
