The year before, Nyren’s lab had also spun off a company, Pyrosequencing AB, to refine and commercialize the technology. Pyrosequencing was not the firm that would bring the technology to market, however; that distinction went to Connecticut-based 454 Life Sciences, who licensed whole-genome pyrosequencing applications in 2003. 454 made chips which enabled highly efficient, parallelized sequencing reactions and released the GS20 sequencer in 2005 for the price of $500,000. The GS20 worked by attaching each individual DNA template molecule to a bead and copying it many times using polymerase chain reaction (PCR). Each bead was then loaded into a well in a microplate, where sequencing reactions would be carried out. The light from luciferase activation could be detected through the bottom of the wells, enabling sequences to be read.
The cabin crew had just served breakfast when Dzafran Azmir felt the first tremor. He and the other two hundred and ten passengers on Singapore Airlines Flight SQ321 had been in the air for more than ten hours. Their flight had taken off the night before from the United Kingdom, where Azmir was studying audio engineering at the University of Plymouth, and had flown across Central Europe, the Black Sea, Turkmenistan, and Pakistan. They were thirty-seven thousand feet above the Irrawaddy River, in Myanmar—three hours from their scheduled landing in Singapore—when the turbulence started. For a moment, the plane quivered around them like a greyhound straining on a leash. Then it lifted its nose and leaped forward on an updraft. Eleven seconds later—at 7:49:32 A.M. on May 21, 2024, according to the flight’s data recorder—the pilots switched on the “Fasten Seat Belt” sign and told the flight attendants to secure the cabin. They were in for some rough weather.
