While assigned to VMFA-235, Wilcutt attended the U.S. Navy Fighter Weapons School ("TOPGUN"), and made two overseas deployments to Japan, Korea, and the Philippines.

While assigned to SATD, Wilcutt flew the F/A-18 Hornet, the A-7 Corsair II, the F-4 Phantom, and various other aircraft while serving in a wide variety of projects and classified programs.

Real-time crew observations of environmental conditions, along with over 14,000 photographs, aided the science team in interpreting the SRL data.

STS-79 Atlantis (September 16–26, 1996), the fourth in the joint American-Russian Shuttle-Mir series of missions, launched from and returned to land at Kennedy Space Center, Florida.

STS-79 rendezvoused with the Russian Mir space station and ferried supplies, personnel, and scientific equipment to this base 240 miles above the Earth.

The five astronauts and two cosmonauts delivered more than 6,600 pounds of supplies and installed batteries, power converters, life support, and exercise equipment on the Space Station.
