I was looking at the Passur website, you know the site that shows the air traffic control images of planes landing and taking off. I was looking at SDF (Louisville)for this morning at 12a-12:30a to see the UPS movements and I saw three go arounds within about 15minutes. I didn't realize how busy it got there.
First is a DC-8 from MKE that does a quick circle over the river, then less than 5 minutes later a UPS 757 from OMA does a goaround. Wait another 5-10 minutes and you will see a Southwest 737 do a go around.
