What if the solution to decades of airport noise and community impacts has been hiding in plain sight all along? In this open letter to city managers across airport communities, we revisit a landmark yet largely forgotten document: the Sea-Tac Communities Plan of 1976. Built on the Port of Seattle's promise — *"As we do better, you'll do better"* — this collaborative plan was supposed to be the long-term answer for neighborhoods living under the flight path. So why has it been reduced to little more than an expensive property buyout program? The answer reveals a critical gap that neither elected officials nor community advocates can fill alone. Real, lasting solutions require sustained professional commitment to airport community planning — something that should have been established 50 years ago. If you work in city management, this episode speaks directly to you and the unique role only you can play in finally delivering on that broken promise.

**Discover why environmental progress stalled for airport communities while cars got cleaner**
Ever wonder why your car's emissions have dramatically improved over decades, but aviation seems stuck in the past? In this eye-opening episode of The Airport Communities Podcast, we explore the fascinating tale of two environmental paths that diverged after 1970.
While Washington Senator Scoop Jackson spearheaded NEPA—one of the largest expansions of environmental policy in American history—and California secured game-changing carve-outs in the Clean Air Act that led to massive air quality improvements, aviation somehow got left behind. Despite Boeing being headquartered in Washington, aviation environmental standards never caught up.
UW Meteorologist Cliff Mass delivers some stark perspective: those two annual flights to Europe generate more greenhouse gases than most people produce in their entire homes over a year. Meanwhile, Boeing's monopoly status has eliminated market incentives for cleaner technology.
This wasn't an oversight—it was intentional. Today, every airport community continues paying the price for decisions made decades ago that exempted aviation from automotive-level engineering standards.
