Tonight I received a call from Lisa Hosinski from Orange County, California (Citizens for No Plane Noise). They knew from my website that Maryland Citizens are concerned with the extra plane noise created by the new Next-gen FAA routing policy at BWI. They want to exchange some information with the group here, leading by Paul Verchinski.
I am sharing their slides here and they proposed a solution too. I wish the coordinated effort across the country will mitigate plane noise from Nextgen soon.
