NASA pilots are now warning Marylanders to be on the lookout as their planes fly as low as 1000 feet off the ground in the coming month.

WASHINGTON (WJZ)—Don’t panic if you see large planes flying unusually low over Maryland roadways next week. It’s all part of a major plan by NASA to help study air pollution over major cities.

Derek Valcourt explains where you’ll be seeing some of those low-flying planes.

The study will focus on air pollution over many of Maryland’s major roads, from Baltimore’s beltway, to the 95 corridor, even over the Chesapeake Bay Bridge.

This is no ordinary plane, it’s a specially fitted NASA aircraft designed with equipment to measure air pollution levels in flight. And starting next week the skies over Maryland will become a pollution detection playground for the plane and for NASA scientists.
