On November 29, 1972, a hearth broke out within the high-rise Rault Heart, in downtown New Orleans. As firefighters struggled to achieve the blaze and tv cameras rolled, 5 ladies trapped in a magnificence salon on the fifteenth flooring needed to make an inconceivable choice: stay within the burning constructing, or leap.
One after the other, they jumped, aiming for the roof of a neighbouring six-storey constructing. 4 of the ladies died.
On the time, a 46-year-old engineer and fellow New Orleanian had been toying with an thought which may have saved them. The tragedy spurred John T Scurlock into motion.
He wished to engineer an inflatable cushion that would present a protected touchdown for folks plunging from nice heights. However to do it, he wanted the assistance of his sons.
First, he obtained them to push 45kg (100-pound) rolled-up items of vinyl off the highest of his workplace constructing and onto the cushion he had designed under. The vinyl was connected to an accelerometer, which helped John calculate the load the cushion may take in at completely different speeds.
As soon as he was assured it was protected, it was time for the following step: having his sons leap off the roof.
“We have been like 10, 12, 14 years outdated, and we have been leaping off a constructing into a giant airbag. It was lots of enjoyable,” recollects Jeff Scurlock, now 66.
‘House pillow’
The next yr, John patented the protection air cushion, the massive, inflatable pad nonetheless used right this moment by hearth brigades from New York to Tokyo to rescue folks from fires and deaths by suicide.
Nevertheless it was not his first invention. In actual fact, his life-saving inflatable was drawn from his earlier invention: the ever-present truthful attraction recognized by many alternative names – the bouncy fort, moon bounce, bounce home or area stroll, relying on the place you’re bouncing.
Within the Scurlock house, it was often called the “area pillow”.
A yr after John filed a patent for the core of what would turn into the area pillow, he began working at a NASA facility in New Orleans. It was 1961, and NASA had opened its doorways three years earlier in response to the Soviets pulling forward within the area race with the launch of the world’s first satellite tv for pc, Sputnik 1.
The US area company was abuzz with tasks exploring the potential of spaceflight, and by 1960, it had developed an curiosity in designing a crewed, inflatable space station, thought by many to be a needed first step in reaching the moon.
Giant, inflexible area stations would require a number of rocket journeys to convey up the components, however plastic inflatables have been thought of mild, robust and straightforward to move. An inflatable area station could possibly be launched into area with a single booster and unfurl as soon as in orbit. (A meteorite-resistant inflatable space module was despatched as much as the Worldwide House Station in 2016, and NASA engineers are hoping to construct a semi-permanent moon habitat out of inflatables.)
John discovered himself in the course of this innovation, which continued even in his spare time, when he would sketch designs for and sew his proto-space pillow, utilizing a industrial stitching machine he arrange in a pit within the floor of his storage so he may haul the heavy vinyl materials in the direction of him as he stitched.
When he assembled an early, home made area pillow for his younger sons to play with within the yard, it quickly grew to become an enormous hit with the native youngsters.
“We have been extremely popular youngsters then, as a result of we had one completely in our yard,” says Jeff. “The entire neighbourhood would come and leap on it.”
Jeff says it was his mom, Francis, who recognised how a lot youngsters cherished the inflatable and obtained the concept to promote it. Finally, John left his job to pay attention full-time on the “area pillow”.
Inflatable options
In 1968, they began promoting the invention to festivals across the nation. However the security dangers have been severe. “It was a nightmare, safety-wise,” says John’s grandson, Mials, 35. “It had no assist, no netting, no strategy to hold you on it.”
When a carnival employee broke his neck and died, the corporate was “sued out of existence”, Mials says.
Not a small yard enterprise, the design wanted protecting options.
John set to work designing enhancements: the area pillow grew columns, cushioning partitions, netting across the sides and a roof, making it far safer. In 1972, the final yr man walked on the moon, the household launched a brand new firm, referred to as House Stroll Inflatables, to fabricate and lease inflatables within the Louisiana metropolis of Kenner.
At present, the worldwide bounce home market is value $4bn, pushed by the recognition of leases.
However as his invention ballooned in recognition, John additionally turned his consideration to fixing issues with heavy-duty inflatables.
Inflatable engineering is deceptively complicated and requires answering mathematical questions to show a 2D material right into a 3D form, says Dr Benjamin Gorissen, a professor of inflatable mechanics at KE Leuven in Belgium.
John cherished numbers, recollects Mials, and was “a man who may do the maths”. He filed patents on a number of constructions, together with one supposed for underwater pipe welding for offshore oil platforms, which resembles a human heart with somebody working inside.
“No matter information article would occur, he’d be in his workplace, sketching out an answer,” says Mials.
Jeff recollects his father studying about sunken submarines within the newspaper, after which engaged on an invention that would assist to resurface them.
Up till John’s loss of life in 2008, “he by no means actually stopped working”, says Jeff. His final creation in his 80s was a large inflatable palm tree, a form of air sculpture meant to offer shade over a 2.8 sq. metre (30sq ft) space.
John didn’t got down to construct a enterprise empire, Jeff and Mials, who now run the enterprise, observe. Although bouncy castles stay the core of their enterprise, the Scurlocks proceed to supply security air cushions, which have a extra complicated construction. Their most heavy-duty product is licensed for 20 storeys, or 200 feet (60m).
Because it was invented, the protection air cushion has saved 1000’s of lives world wide, nevertheless it all started with an early, devoted pioneer urging his youngsters to leap off the roof.
