Preston Hollow neighbor Victor Vescovo made a name for himself exploring the deepest parts of the ocean, but earlier this month, the explorer took to the skies.

He and fellow St. Mark’s School of Texas graduate Alan Stern shared a Zero-G flight from Denver.

Stern, class of  1975, is best known as the principal investigator of NASA’s New Horizons mission to explore Pluto and the Kuiper Belt.

Looks like these two explorers had a blast defying gravity. See more photos here.
