Climb commenced one mile south of Fort Bliss, Texas, with the airplane climbing from 4,704 ft asl to 36,592 ft asl, a gain of 31,888 ft achieved in 16 minutes while covering 104 nm.

The first cruise segment began 12 nm south of the 68NM Flying H Ranch Airport, Mayhill, New Mexico, and persisted for 151 minutes, during which 799 nm were flown at level altitude.

Descent started overhead Warsaw, Illinois, from 37,000 ft asl down to 30,997 ft asl, a loss of 6,003 ft in 3 minutes, covering 27 nm.

A brief cruise followed one mile south of Blandinsville, Illinois, lasting 2 minutes and spanning 13 nm.

The next descent began 3 nm north-west of IL15 Runyan Aviation Airport, Bushnell, Illinois, descending from 31,008 ft asl to 10,004 ft asl, a reduction of 21,004 ft over 12 minutes and 82 nm.

A short cruise segment then started 6 nm south-east of Deer Park, Illinois, lasting 2 minutes and covering 8 nm.

Descent resumed 4 nm south-east of Ottawa, Illinois, from 9,999 ft asl to 6,487 ft asl, a decrease of 3,512 ft in 5 minutes, traversing 24 nm.
