I understand it was a military airfield and that the only
approach aid was radar. I forget the term - Precision
Approach Radar (PAR)? This is normal in some militaries
and works very well. The operator has two screens one for
azimuth and the other for slope. He "talks" the pilot
along the glideslope to minimums. I have no idea what
typical minimums might be.

Gosh, I didn't think my IFR training was THAT long ago....I remember
studying and (I think) actually doing at least one PAR (Precision
Approach Radar) during my IFR instruction. This was early 90s and I
remember it well because somebody (instructor, perhaps) asked me at
one point "What are the only two precision approaches available for
IFR?" I could only answer "ILS," but then I was introduced to PAR. I
am sure we did one, too, which I think caught the tower off guard
because nobody ever did a PAR. There's talk here about a trailer or
something at the runway's end but I believe tower provided the
guidance for that one PAR I did.
