On October 20th, 1980, Ronald Reagan wrote the president of the air traffic controllers' union a letter calling their working conditions "deplorable" and promising his administration would fix them. PATCO endorsed him three days later. It was the first time the union had ever backed a Republican.

Ten months into his presidency, 11,400 controllers walked off the job. Reagan gave them forty-eight hours to come back. When the deadline passed, he fired every single one of them, broke the union, and dared the FAA to keep the planes flying with less than a third of its workforce.

The planes kept flying. The consequences took longer to arrive.

This week we hit Control Z on the forty-eight-hour deadline, and follow what happens when the president who promised to fix the system decides not to destroy it.

On a computer, Control Z is the undo button. When you press it, whatever you just typed gets reversed and allows you to make a different decision.

What if you could press control Z on some of the biggest decisions in history?

In October of 2016, Bob Iger was 48 hours from buying Twitter for $15 billion. Both boards had approved. The lawyers were drafting. Goldman Sachs was working the weekend. Then Iger went through the user data one more time, read his own notifications, and couldn't sleep. Sunday morning he typed an email to his board with the subject line "cold feet," called Jack Dorsey, and killed the deal. Twenty-eight days later, Donald Trump won the presidency.

Fourteen months after that, Disney bought 21st Century Fox instead, and Disney+ followed.

This week we hit Control Z on the Sunday morning phone call, and follow what happens when the man who runs Disney decides to own the platform that hosts the president.
