- Competitors must make an 11-feet jump from a mini tramp to a set of handles that swing independently of each other, kind of similar to The Clacker.
- Then, they must build enough swing and momentum to make a transition to the next set of handles, which are also 11 feet away from the first set of handles.
- After that, they must build enough swing and momentum to make a 10 feet transition to the Rope Ladder, and climb it to reach the buzzer before the time ran out, in order to clear the stage.
This obstacle was proven to be much difficult than its predecessor (the Triple Swing), as competitors like Ryan Stratis, Jon Alexis Jr., Nick Hanson, and Dan Polizzi failed on this obstacle. In its first appearance, only 17 competitors could complete the obstacle within the time limit, and advanced to Stage Two.
However, unlike on American Ninja Warrior 8, 51 competitors could reach the obstacle, and only 10 competitors failed, including Brandon Pannell, Jesse Labreck, Ben Baker, Chris DiGangi, and most shockingly, Jessie Graff (who completed this obstacle on the previous season, setting a history as the first woman to complete Stage One on American Ninja Warrior).
The Flying Squirrel appeared on Ninja Warrior UK 4, as the fourth obstacle in Heat 2, and was called as the Cargo with Squirrel. However, compared to the one used on American Ninja Warrior, the obstacle featured:
- No trampoline,
- Only one set of handles was used, and
- The cargo net was similar to the one used on the Jump Hang. Therefore, after reaching the cargo net, competitors must climb down the cargo net instead of up.
- With only 17 competitors could complete the obstacle within the time limit, and advanced to Stage Two, American Ninja Warrior 8 is currently holding the record for the lowest amount of finishers during Stage One in American Ninja Warrior history, beating American Ninja Warrior 6's Stage One at 18 finishers.
- With 41 competitors completed the obstacle within the time limit, and advanced to Stage Two, American Ninja Warrior 9 is currently holding the record for the highest amount of finishers during Stage One in any SASUKE/Ninja Warrior international format, beating American Ninja Warrior 7's Stage One at 38 finishers.
