Figures resembling oversized flying squirrels will be visible for a short period of time in Denver Tuesday evening when professional base jumpers take on a 42-story flight downtown.

Red Bull Air Force athletes Jeff Provenzano and Miles Daisher will attempt to land in the outdoor swimming pool at Four Seasons Hotel Denver, 1111 14th St., after hurling themselves from the skyscraper’s 45th floor.

Thirteen professional skydivers, base jumpers and para-glider pilots comprise the Red Bull team, which makes its Denver debut Tuesday. The daredevils, all men, conduct more than 50 stunts in a year and have incorporated 13 buildings around the country.

The pair will jump between 7:30 and 8 p.m. Tuesday as part of Four Seasons’ Summer Soiree. The event, taking place from 6-9 p.m., is expected to draw about 200 people to the pool terrace.

The spectacle, however brief, will also be visible from the street.
