> Nobody puts airports inside city centers

Taipei Songshan, Boston Logan and the old Hong Kong Kai Tak to name a few.

Boston Logan is surrounded by water to the point only one end of a single runway isn’t aimed directly at water soon crosses water. The city center requires crossing a bridge. Taipei is a little worse but its only runway is going next to a river here and aimed at a park on each side.

Hong Kong Kai Take would be a solid example except it closed in 1998 because of how the city grew. Look at maps from 1950 and it doesn’t look like a bad location for a small airport.

The Big Dig helped a lot, although sometimes that can get pretty backed up too. > Look at maps from 1950 and it doesn’t look like a bad location for a small airport. Generally, airports that are close to major urban centers were developed prior to 1950, including all 3 examples named. Songshan was opened during Taiwan's colonial period as the “Matsuyama Airdrome” serving Japanese military flights (https://www.sups.tp.edu.tw/tsa/en/1-1.htm). For bigger cities with these old central airports, larger airports were opened later in many cases. I don't think that will ever happen in Boston, although satellite airports in neighboring states like "Manchester-Boston" or TF Greene in Rhode Island try pretty hard.
