removed the background sectionEdit
The Union Army Balloon Corps operated and/or built eight hydrogen-gas balloons from 1861 – 1863.
- Small balloons: Enterprise, Eagle, Constitution, and Washington
- Large balloons: Union, Excelsior, Intrepid, and United States
- This is off topic and excessive for being so; I've put in an external link and a small new note saying one of the balloons was called enterprise to compensate. -- Capricorn (talk) 12:21, April 19, 2015 (UTC)
