Although the day started with difficulties, it ended with a successful 1000 foot space elevator test climb to a tethered 10-foot diameter balloon - LiftPort's first really significant climb. This was supposed to be a 1 mile climb test, but the FAA-required aviation orange paint - applied at 50 foot intervals to the ribbon - contained acetone, which weakened the ribbon. The first two attempts of the day resulted in ribbon breaks due to this acetone-induced degradation.
