Before you start calling MUFON, you might want to know about the Bullet 580. The 235 foot airship is scheduled to make it's first flight later this month.
E-Green acquired airship builder 21st Century Airships, which holds patents for Bullet 580 technologies and designs, including a system of bags that hold helium for lighter-than-air lift and an inner hull that is filled with ambient air.
The eight million dollar Bullet 580 is designed to lift payloads weighing up to 15000 pounds. With a top speed of 80 mph, it will also be able to reach 20,000 feet for surveillance operations.
The first flight will be from the Kennedy Space Center, Florida.
