the point i want to get to with Thompson’s paper is that the last few sentences of Thompson’s original paper actually mention the possibility of intersection and complement (below), but the funny thing is that this footnote has been forgotten for decades, and no one ever followed through.. and for the ones who tried, in fact, it wasn’t so easy in Thompson’s NFA framework at all, the devil is in the details.

Wadler’s own worst flight was through Hurricane Ian, in 2022—a trip famous for its furious lurches from side to side. But that flight came in second on his list. The bumpiest of all was through Hurricane Hugo, east of Barbados, in 1989. “It was like riding a roller coaster inside a car wash,” Frank Marks, a NOAA meteorologist who has flown through more than a hundred hurricanes, told me recently. “Within less than a minute and a half, the wind increased to a hundred and seventy miles an hour. And then, just as we’re breaking into the eye, starting to see a little clearing ahead, a little sunlight, someone says, ‘There’s a flame coming out of engine three!’ And we think, Oh, crap.” Their plane, a Lockheed P-3 Orion, nicknamed Kermit, lost power in engine three and fell more than six hundred feet, nearly into the Atlantic. It pulled out of the dive and climbed back into the eye of the storm. Then it circled there for about an hour before an Air Force plane escorted it through a soft spot in the eye wall.
