The team found what they were looking for during one of the Predator’s very first split operations missions in early September 2000. Swanson was circling over Tarnak Farms, a walled compound near the Kandahar airport where bin Laden-or UBL as the team called him, referring to the alternative spelling, Usama-was thought to be living. Jeff Guay, an Air Force master sergeant on the team, was controlling the drone’s camera. Sure enough, a man in white, surrounded by an entourage, soon emerged on their screens.

“When UBL walked out of that one building,” Swanson says, “the way he appeared much taller than everybody, the people were deferential around him, the way he was dressed, Jeff and I just looked at each other and it’s like, ‘Yeah, that’s got to be him.’” Swanson assumed a cruise missile would be dispatched in the direction of bin Laden while the Predator loitered overhead to make sure he stayed put. The team had been instructed to continue circling for as long as necessary, even if that meant running out of fuel and crashing.

But for reasons obscure to the team, no strike was ordered. With Swanson gripping his joystick, unable to do anything but stare, America’s final chance to kill Bin Laden before September 11 slipped away.

In a Daily Beast special report, I examined a scenario in which a fire in the forward cargo hold of the 777, originating in a consignment of lithium-ion batteries that were being shipped on the airplane, could have breached a wall and reached the Main Equipment Center, seriously degrading the airplane’s avionics and leading to the incapacitation of the crew and passengers.

However, the avionics for the Satellite Data Unit, sending the pings, was located not in the Main Equipment Center but well clear of it, in the roof of the cabin behind the wings, because that is where the antenna to access the satellite is best positioned.

The picture in the Australian report of an airplane stricken by a sudden and extensive loss of electrical power, while in no way definitive, is entirely consistent with this scenario.

Indeed, the report gives dramatic new clarity to the “zombie flight” version of events in which the airplane, by then fatally crippled, makes one final change of course and then flies into the vast emptiness of the southern Indian Ocean without any sign of human direction or control.

This is how you derail a therapy session: In the middle of a carpeted room with calming pot plants stooped weakly in softly lit corners, you tell a 65-year-old qualified mental health practitioner, beneath her framed medical degrees and her various accomplishments, that she doesn’t understand the American film director Michael Mann, who is not Michael Bay.

There’s a thing that happens in Michael Mann movies where too much stuff gets on top of a person and that person just burns their life to the ground and moves on. It happened in Thief – James Caan drops his bulletproof vest on the street and walks off. It happened in Heat – de Niro leaves his girlfriend in the car and disappears in the crowd. They shed the material, the personal, the emotional, their car, their girl, and they walk away.

I explained that Michael Mann film colours are a whole palette on their own, that they’re blue and orange and saturated but washed out at the same time, and that it’s weird how the colours are so strong because Michael Mann films are about men who feel nothing. The men in Michael Mann movies are obsessive and dead inside; saturated and washed-out at the same time. They don’t even feel the emotion of vomit. As a mode of dealing with a white noise of emotion in your own personal world, a Michael Mann movie is like taking an emotional sleeping pill.

He was like one of those characters in an 18th-century comedy meant to embody a particular flavor of human folly. Trump struck me as adolescent, hilariously ostentatious, arbitrary, unkind, profane, dishonest, loudly opinionated, and consistently wrong. He remains the most vain man I have ever met. And he was trying to make a good impression. Who could have predicted that those very traits, now on prominent daily display, would turn him into the leading G.O.P. candidate for president of the United States?

His latest outrageous edict on banning all Muslims from entering the country comes as no surprise to me based on the man I met nearly 20 years ago. He has no coherent political philosophy, so comparisons with Fascist leaders miss the mark. He just reacts. Trump lives in a fantasy of perfection, with himself as its animating force.

These questions should inspire two feelings. The first is humility. We can never know what a universe without Hitler would have looked like. But the implicit argument that his removal would improve history must also consider that his removal could make it worse. Indeed, recent experience should make us doubt our abilities to bend the course of human events towards our will. The Bush administration naively claimed that toppling Saddam Hussein in 2003 would produce a vibrant liberal democracy in the largely illiberal Middle East. Instead it brought about regional instability, ethnic cleansing, civil war, and ISIS.

The second is relief. We live in cynical times, which masks the fact that we live in extraordinary times. Atrocities still occur, but human rights are now a normative value throughout most of the world, even if their enforcement is imperfect. Conflicts are still fought, but the great powers have avoided another world war for seven decades. Racism and anti-Semitism still exist, but pre-war forms of colonialism and pogroms have largely disappeared. This is not the future for which Nazi Germany fought and fell. Removing Hitler from history would gamble with one irrefutable truth: He lost.
