Unusual landing in MSP from ATL by Delta

Anyone know about a quick maneuver by a Delta flight arriving morning or early afternoon of 12/27/10 into MSP from ATL? Probably Flight Nos. 340 or 400?

thanks

Umm,

So which one is it? Morning or afternoon?

Are we talking around 12pm here? Plus or minus an hour?

What type of aircraft was it? (B737, MD88, MD90)? Obviously you saw the maneuver, can you describe it?

If I had to guess I would say S-Turns for spacing?

That would be my guess
