This simulation uses the same conditions as in the primary freefall simulator, but with the jump order reversed. Here, the slow faller exits first, followed by the fast faller 10 seconds later. Notice that around 6,000 feet, the fast faller passes up the slow faller, but with greater horizontal separation than was provided by the delay between the two groups. The horizontal separation at opening is around 1,400 feet. Kudos to the T-squared Wagner team at Omniskore.com for developing this animation based on John’s program.
