| | Atlas (Site not responding. Last check: 2007-10-09) |
 | | The Atlas structure in fact was not strong enough to support the weight of propellant and payload; the interior of the Atlas had to be pressurized to prevent the rocket from crumpling under gravity. |
 | | It was an Atlas A, one of six slightly different types A, B, C, D, E, and F. The Atlas A suffered a failure of its structure soon after liftoff, causing it to collapse and explode. |
 | | Atlas II is available in several versions: the standard Atlas II (6,500 pounds or 2,900 kg to geosynchronous transfer orbit/GTO); the Atlas IIA with upgraded second stage (6,760 pounds or 3,070 kg to GTO); and the Atlas IIAS with four solid rocket boosters (8,200 pounds or 3,720 kg to GTO). |
