As a pilot (small plane), I have flown into many large airport(ATL, Share) as well as many small ones. Some of the moderate size airports have control towers open some hours and are "uncontrolled" the remainder of the day.

Pilots are trained to communicate and coordinate their own arrivals and departures for these situations and looking at the average volume of flights going into and outbound from EIS(ie EIS is not a busy airport), I am surprised that the government shut down the airport vs continuing to operate without a control tower.

Again, the government seems to disappoint(airport closure) what should be a marketing boost (MIA to EIS flight).

Hopefully they get this rectified fast!
