Whatever group of people engineered self-inflating airplane emergency slides deserve many awards. It’s absurd to see something that big emerge from something that small in such a short amount of time:
As for how and why this guy is tasked with doing this in a driveway: The video is from a Dutch company called Aircraft End-of-Life Solutions, who recorded it in December of a previous year. As the name suggests, AELS dismantles and recycles decommissioned airplanes, and blowing the slide was part of their “End of the year clean up.”
