Our plane landed at 1:07pm (United out of Newark) yesterday, Sunday. There was no one ahead of us in Immigration, but when we went to baggage clam we noticed a mob of people waiting to exit. After we got our bags we joined to mob. It was a free for all trying to get to the point where the line was within the "ropes". The line moved though slowly. Eventually we got to the end. Customs has a huge new machine, an X-ray scanner of some sort. Everyone was required to plane everything, including carryons and purses on the scanner belt one item at a item. What a mess. Didn't exit the airport unit 2:00pm. Can't imagine what it's like when there are multiple planes arriving. If they are going to do this they need more scanners and a lot more organization in the arrivals hall .
