Takeoffs a problem for giant bird
Jul 2 2007 10:00PM (CT)
WASHINGTON (AP) - Weighing in at 150 pounds or more, the all-time biggest bird couldn't just hop into the air and fly away, researchers say. A team led by Sankar Chatterjee of Texas Tech University used computer programs originally designed for aircraft to analyze the probable flight characteristics of Argentavis magnificens, a giant bird that lived in South America 6 million years ago. Like today's condors and other large birds, Argentavis would have had to rely on updrafts to remain in the air
