Their Save Our Heritage nonprofit is up against the Heritage Foundation. They're almost guaranteed to lose out.

While noble in intent, the protest itself was incredibly stupid and dangerous.

I am a pilot that flies into Hanscom Field and I remember the day of the protest. It was low ceilings, so visibility. You don't see the runway until the last 400 feet and that 400 feet goes very quick once you pop out. The protesters chose to stand on the runway in these conditions at great peril to themselves, flight crew, and passengers.

People have been trying to get this airport shut down for years due to noise. It's very hard to convince people that homeowners (of properties worth multiple millions of dollars) who have been complaining about noise from the airport for 20 years suddenly care about the environment.

Hanscom already sees tons of jet traffic, with many landing, unloading passengers, and flying to another airport storage (ferry flights). While there is bound to be some induced demands from hangar expansion, the runway utilization is already maxed out. There are long wait times for takeoff because of all the traffic. Aircraft are told to hold or circle to deconflict landings. Hangar expansion will reduce the number of wasteful ferry flights.

Not to mention that the area where the hangars are being built is currently a toxic waste hazard from the US Air Force. In fact, old Air Force hangars still exist on that side of the airport, but no one is allowed to go over there because of the toxic waste. This hangar expansion will clean up that toxic waste.
