A new video features supermodel (and super sweetheart) Kate Upton posing for her latest photoshoot in zero gravity. Her delightful shoot was for the 2014 Sports Illustrated Swimsuit Issue, which can be found on magazine stands since Tuesday, February 18.

While a supermodel photoshoot would usually be irrelevant on a nerdy motor site, Kate Upton and her team of Sports Illustrated photographers made a very interesting choice in studio: a highly modified Boeing 727 jet airplane also known as "G-Force One."

As the name G-Force One implies, the radical tri-jet aircraft performs 90 to 100 minute that perform 15 parabolic arches. The pilot points the G-Force One towards the sky at a steep 45 degree climb until it hits 34,000 feet. When reached, thrust is reduced to recreate a remarkable zero gravity experience. Free fall lasts for approximately 20 to 30 seconds before thrust is re-engaged at a controlled altitude.

15 parabolic arches sounds nauseating, but a weightless Kate Upton performed the cutest pretzel barrel rolls with ease as the photo team encouraged her to "Keep that face pretty, sweetie!" According to the crew, zero gravity also managed to keep wardrobe malfunctions to a minimum.

The G-Force One is owned and operated by the Zero Gravity Corporation, based in Arlington Virginia. Unlike the NASA trainer program, G-Force One is a civilian service attracts adrenaline junkie tourists and private researchers alike. Interested in an adventure yourself? A weightless flight on the G-Force One will cost $4,950.

A Kate Upton story on an auto site will seem contrived, but this isn't the first time she landed on our headlines -- remember the Mercedes-Benz CLA Super Bowl commercial? The 50th anniversary issue of the swimsuit issue hits newsstands today. Be sure to watch the lovely Kate Upton in the G-Force One Boeing 727 aircraft in the video below (remember to pick up your jaw):
