The unmanned Global Hawk aircraft checked out a tropical depression in the Atlantic Tuesday morning, said the National Aeronautics and Space Administration.
This is a new way to keep track on storms. The depression turned into Tropical Storm Nadine later in the day, but the estimated track of the storm keeps it well away from Costa Rica. Like many Atlantic storms Nadine appears to be taking a north and east track and curving away from the Caribbean. It carries 40-mph winds.
The space agency said that the unmanned craft also overflew Hurricane Leslie in the mid-Atlantic. This is the first time that the agency is flying Global Hawks from the U.S. East Coast.
The advantage of an unmanned craft are clear when the agency notes that the flight Tuesday morning was 26 hour
