Around 5:30pm central time, as I was taking a walk in my hometown of Milwaukee, WI, I saw a large contrail approaching from the northeast. At first I expected to see a 747, however, as the aircraft drew closer its contrail dissipated and it appeared to have descended as well as slowed. Upon closer inspection it appeared to be a high-wing 4 engined jet with a T-tail. It didn't fit the profile of a C-17, so my best guess is that it was a C-5. However, I have seen an Algerian Air Force IL-76 in MKE before, so I wonder if perhaps we had a visitor from another country?
Does anyone have any info on a large military transport coming into either MKE or MSN (or maybe ORD, though it seemed too low and headed in the wrong direction for ORD to be likely) ?
