JUMPING FROM SPACE 101 ALAN EUSTACE TALKS US INBY ANNETTE O’NEIL o, late in the fall of 2014, you watched Alan Eustace get tugged 25 miles into the stratosphere by a balloon that for all the world looked like a big, white map pin. You checked out the milky curve of a somersaulting Earth through the bare Sbubble of his helmet. You may have even giggled a little bit at what it looks like to land a parachute when you’ve been immobilized into the shape of a gingerbread man. You may have even thought, “That’s just a prohibitively expensive belly jump. I could totally do that.” Okie dokie, armchair astronaut. Before you start calling national space programs with your elevator pitch, let’s talk about what it’s really like to skydive from space. There are precious few people on the planet who can speak from that experience. Luckily, Alan Eustace is happy to tell you all about it. “It was so different from any other skydive I’ve ever done,” he began. “It is hard to even describe. It’s so hard that you can’t even effectively use skydiving as a basis to describe the differences … or find any similarities, for that matter.” YEAH. IT’S LIKE THAT. To start to find a framework, let’s start where Eustace started: in training. Secret training. Eustace and his cohort went to a handful of drop zones to get the job done: Skydive Perris in California and Skydive DeLand in Florida for much of it, then undisclosed locations in Coolidge, Arizona, and Roswell, New Mexico, for the super-secret-squirrel stuff. He and his project partner, friend, instructor, coach and tutor—Daniel “Blikkies” Blignaut—ran the numbers and tested max exit weights to figure out how the canopy flight and landing would work. To do so, they went out as a tandem with Eustace in the back and Blignaut in the front. The pair had a 70-pound bundle in front of them, covered with camouflage. “If anybody ever asked, it was a military-related project,” he said, grinning. “No one ever questioned the fact that we were going out with an exit weight of 550 pounds.” They would have started asking questions, of course, if Eustace had been wearing his space suit. 82 | USPA.ORG | PARACHUTIST | OCTOBER 2019 JUMPING FROM SPACE 101 UNLEARNING EVERYTHING PITCHING AND SPINNING The suit was the key to the entire enter- Right.

But just the act of getting to that push-to-talk switch, pushing it and releasing it used a lot of energy, and we were saving all energy for freefall and for the canopy ride.” Eustace pre-breathes oxygen prior to his jump.

With that waypoint behind him, Eustace deployed his canopy. During a test, Eustace practices landing his canopy wearing full “Since [former record holder] Felix [Baumgartner] spun so badly [on his equipment. Photo by Volker Kern. 127,852-foot world record jump in 2012], I was obsessed with holding head- ing,” Eustace recalled. “[This] required a really delicate touch, since even the smallest of movements above Mach 1 have a big impact on your direction.” He continued, “I was supposed to pull at 10,000 [feet]. I started the pull sequence at 12,000, but since I can’t see the handles, there is an exact se- quence that I have to go through to make sure I pull the main rather than the cutaway handle. I went through it, but as I pulled, my hand slipped off, so I had to go through the sequence again. I laughed at myself, since I had 126,000 feet to get a firm grip on the handle, and because I was obsessed about directional control, I waited until the last minute.” “We had set it up so [Blignaut] was flying in a Kodiak [airplane],” Eustace said. “He jumped out and opened above me, and then he was my wingman on the way down. The moment I opened, within about a minute, my best friend on the project was open and flying right next to me. He was on the radio to tell me about any fences or obstructions, because it is hard to see in that suit.” Blignaut landed about 20 seconds before Eustace in distinctly light- and-variable conditions.
