Watch: 94-Year-Old Daredevil Breaks Wingwalking World Record

Ninety-four-year-old Tom Lackey cemented himself as the world's coolest grandpa this past week, becoming the first person to wingwalk the 26-mile journey from Land's End to the Isles of Scilly.

In case you don't know what wingwalking is, well, it's exactly what it sounds like. Watch:

Lackey is no stranger to daredevil aerial feats, holding the record for oldest person to complete a loop-the-loop while standing on the wings of a plane, as well as the record for oldest man to complete a wingwalking round trip from Dover to Calais.
