I decided to go planewatching yesterday afternoon. I wanted to sample a couple of potential new places. They were all on Middlebelt Road. They give pretty good views of planes as they are landing at 21L and 21R. I'd imagine the views as they takeoff to the north would be pretty good too.
Since there are a bunch of flights that arrive from Europe between noon and 2:00 in the afternoon, I decided to go over there. They are most of the heavy aircraft that land at Metro it seems. Heavy is the air traffic designation for planes that are over 300,000 pounds at take off.
