“An hour and thirty-one minutes after launch, my pressure altimeter halts at 103,300 feet. At ground control the radar altimeters also have stopped-on readings of 102,800 feet, the figure that we later agree upon as the more reliable. It is 7 o'clock in the morning, and I have reached float altitude... Though my stabilization chute opens at 96,000 feet, I accelerate for 6,000 feet more before hitting a peak of 614 miles an hour, nine-tenths the speed of sound at my altitude.” ReadingSoundHoursMorningFeetMinutesFiguresPressureAgreeSpeedMilesNineClockThirtyHittingFloatsHaltRadarOne MinuteAccelerateAgree Upon Author:Joseph Kittinger
