His eyes fall to the floor when I ask him to describe it. We’ve been tiptoeing toward it for 45 minutes, and so far, every time he seems close, he backs away, or leads us in a new direction. There are competing theories in the press, but Joe Biden has kept mum on the subject. I want to hear him explain it. I ask him to walk me through the night he appeared to lose control of his words onstage.

“I—um—I don’t remember,” Biden says. His voice has that familiar shake, the creak and the croak. “I’d have to see it. I-I-I don’t remember.”

We’re in Biden’s mostly vacant Washington, D.C., campaign office on an overcast Tuesday at the end of the summer. Since entering the Democratic presidential-primary race in April, Biden has largely avoided in-depth interviews. When I first reached out, in late June, his press person was polite but noncommittal: Was an interview really necessary for the story?

Astronauts are more than cosmic travelers. They’re also research subjects in the careful study of what exactly outer space does to the human body. On the ground, researchers measure vitals, draw blood, swab cheeks, and more. In orbit around the Earth, the astronauts do the work themselves.

That’s how they found the blood clot.

An astronaut was carrying out an ultrasound on their own body as part of a new study, guided in real time by a specialist on the ground. A similar test before the astronaut launched to space had come back normal. But now the scan showed a clump of blood.

“We were not expecting this,” says Karina Marshall-Goebel, a senior scientist at NASA and the author of the study, published earlier this month. “This has never been reported before.”

Through four long days of impeachment hearings, witness after witness sat passively by as Republican lawmakers responded to their detailed testimony by arguing that President Donald Trump had a legitimate reason to be suspicious of Ukraine, because he believed that the country “tried to take me down” in 2016.

That silence from the witness table ended this morning, as Fiona Hill used her opening statement before the House Intelligence Committee to accuse Republicans on the panel of peddling a “false narrative” that amounted to Russian propaganda.

“Based on questions and statements I have heard, some of you on this committee appear to believe that Russia and its security services did not conduct a campaign against our country—and that perhaps, somehow, for some reason, Ukraine did,” Hill, the former top expert for Ukraine and Russia on the National Security Council, told the lawmakers. “This is a fictional narrative that has been perpetrated and propagated by the Russian security services themselves.”

The flight that put the Boeing Company on course for disaster lifted off a few hours after sunrise. It was good flying weather—temperatures in the mid-40s with a slight breeze out of the southeast—but oddly, no one knew where the 737 jetliner was headed. The crew had prepared three flight plans: one to Denver. One to Dallas. And one to Chicago.

In the plane’s trailing vortices was greater Seattle, where the company’s famed engineering culture had taken root; where the bulk of its 40,000-plus engineers lived and worked; indeed, where the jet itself had been assembled. But it was May 2001. And Boeing’s leaders, CEO Phil Condit and President Harry Stonecipher, had decided it was time to put some distance between themselves and the people actually making the company’s planes. How much distance? This flight—a PR stunt to end the two-month contest for Boeing’s new headquarters—would reveal the answer. Once the plane was airborne, Boeing announced it would be landing at Chicago’s Midway International Airport.

1. The Disappearance

At 12:42 a.m. on the quiet, moonlit night of March 8, 2014, a Boeing 777-200ER operated by Malaysia Airlines took off from Kuala Lumpur and turned toward Beijing, climbing to its assigned cruising altitude of 35,000 feet. The designator for Malaysia Airlines is MH. The flight number was 370. Fariq Hamid, the first officer, was flying the airplane. He was 27 years old. This was a training flight for him, the last one; he would soon be fully certified. His trainer was the pilot in command, a man named Zaharie Ahmad Shah, who at 53 was one of the most senior captains at Malaysia Airlines. In Malaysian style, he was known by his first name, Zaharie. He was married and had three adult children. He lived in a gated development. He owned two houses. In his first house he had installed an elaborate Microsoft flight simulator.
