Of course, this all due to dem small single and twin engine planes dat don't pay user fees to pay for da new radar hardware.
O'Hare Airport's primary radar system shut down twice Friday, delaying many flights at one of the nation's busiest airports.
O'Hare's Airport Surveillance Radar 9 first stopped operating about 3:30 a.m., said Wendy Abrams, spokeswoman for the Chicago Department of Aviation.
The radar was fixed at 9 a.m., but it went down again at 9:35 a.m. and was restored just before noon.
