Pilots will operate the aircraft at altitudes lower than typical commercial flights, executing specialized maneuvers such as vertical spirals between 1,000 and 10,000 feet, circling above power plants, landfills, and urban areas. The flights will also include occasional missed approaches at local airports and low-altitude flybys along runways to collect air samples near the surface.
The East Coast flights will be conducted up to June 26 over Baltimore and near Philadelphia, as well as near the Virginia cities of Hampton, Hopewell, and Richmond. The California flights will occur up to July 2…
