Something going on at KUGN?

I noticed a lot of air traffic going to/from the airport today. So after being done hiking by the lake, I went to see if anything was going on. Well, something was going on. They had squads blocking off the south lot (normally publicly accessible) and ambulances and such ready. Talked to some other person observing and they said there was some aircraft with a gear problem.

But if that's the case, why the extra squad cars. One or two I could understand, but more than a dozen with two or three unmarked? That doesn't make much sense if blocking off the lot was the only thing they needed to do.

It was really tempting to take photos. (I had my gear.) But I figured that would have gotten more attention than I cared for.

If only I knew somebody that lived adjacent. I would have stopped by and done some "spying" from there. ;)

What's the story at KUGN?

This was a few weeks back that I noticed it...

Anyone know what happened to the D.B. Aviation building? Did they move elsewhere in the airport, or what? The building that carried their sign isn't named the same anymore. They still have their website up at the moment. Seems funny though.

Anyhow, during that trip I was looking to see if I could spot some unusual helicopters at the airport. (A Bell-206 or MD-500, but without any ID markings.) Yet at the time there was a huge snow pile by the south lot where they let people watch the planes. So the whole area where they would be parked was obscured.

As for the airport? (For those not familiar.) Not the most busy, mostly C-172s and the like doing casual flying. You also have your mix of kit planes, business/charter jets, and occasionally Coast Guard doing the Lake Michigan patrol or a news or medical helicopter or two.
