✦ THE WOW MOMENT ✦
A firefighter presses one button, and a drone shoots 50 feet up a collapsed stairwell, its tether extending like a yoyo. When the hippo-sonar pings beneath the rubble, the drone's marionette limbs deploy, gripping twisted metal to pull itself toward a trapped survivor—live footage streaming back as the tether retracts smoothly, pulling both to safety.
