The "Dirty Laundry" singer started Saturday's adventure by posting an Instagram video from the ground, instructing fans to "See if you can guess what we're doing today." She then sang along to John Denver's "Leaving on a Jet Plane" and Tom Petty's "Free Fallin," sandwiched by a fun lip sync to the Pointer Sisters' "Jump," before sharing a selfie of her and a friend's "brave faces."
Underwood was so proud of taking such a major leap (pun totally intended) that she posted four photos of the dive. "Still can't believe I did this!" she captioned the first one of her about to jump with her Sydney Skydivers instructor.
As if that weren't enough, Underwood and another pal made a video diary to fully remember how they felt at that very moment. "That just happened. It was awesome," the Oklahoma native said of the 14,000 foot jump, adding, "Very cool. I didn't cry at all."
