Wow! I never thought I would see one of these in the wild. It was in our backyard, flying around and vibrating it's antennae every time it landed. With it's ovipositor it was almost 6" long!

something similar but no pic
I am looking at a large wasp/fly that I've never seen, that is possibly in this family. It is about 1 inch long, with 2-3 inches of tail curved downward. The back end (body/tail?) is jointed about six times, almost spiraled, but not very tightly. The entire insect was black. (no yellow) I think there is 1 set of wings.

Any ideas?

(I am currently high up in a downtown Baltimore, MD office building.)

 
Pelecinid?

 
Yes
That is it exactly. What is it related to, and is it normal to be around here?

likely Megarhyssa atrata
This sure looks like what Eric Eaton has told me is Megarhyssa atrata. See:
Megarhyssa page
I'll write a guide at some point.
