At most major airports someone is paid to chase birds off the runway, but at Sitka’s airport that job is especially challenging. That’s because three-fourths of Sitka’s runway is surrounded by water. Fish spawn along its banks, attracting hungry birds. That problem was highlighted four years ago when two Alaska Airlines jets collided with eagles on takeoff. KCAW’s Emily Forman spoke with the expert who came in afterward to make sure the runway is safe.
