Was there an aircraft parked somewhere in the runway environment
(beyond the hold-short line) between you and the the ILS antennas?
The glideslope signal is reflected off the flat ground between the
antenna and the runway threshhold. Hold-short lines on the taxiways are
placed far enough back from the runway that an aircraft in the runup
area will not interfer with the glideslope signal.

Shouldn't have been. It was right after tower closed for the evening and
the only other aircraft reporting was a National Guard helicopter taxiing
for closed traffic (IFR minimums...low clouds/fog) We had the glidescope,
just not the localizer needle. And we had it on the first approach as well
as on the back course loud and clear. Was just that one time, and it came
around right as I called for missed approach, but that wasn't until I'd
passed the outer marker (I was already climbing out by then. )

We were there. Followed the needle out, did the procedure turn, came back
around, picked up the needle again and the right before the outer marker it
just blipped out and we got nothing.

Given the IMC conditions we didn't ask to be vectored to try again, but it
was a great learning experience anyway.
