The following contains spoilers for episode 1 of Loki.

The MCU isn't new to inserting certain Marvel characters into historical events, and it's fun to see because it allows these characters to be a part of our real history. For instance, Captain America fought in World War 2, and though he was often fighting fictional enemies, it still grounds him in the real world, and sometimes it's fun to consider that revisionist history.

From what's been shown in the trailers and the first episode, it seems as though Loki is going to involve the titular character traveling through time to fix mistakes in the timeline and likely inserting himself into certain historical events. Marvel even managed to slip one of these pieces of revisionist history into the first episode, where they insert Loki into one of the most famous real-life mysteries of the past 50 years.

In the episode, there is a scene in which Mobius (Owen Wilson) is questioning Loki (Tom Hiddleston) and replaying various scenes from his life. This is when we get a flashback sequence that involves Loki sitting on a plane, in a very different look for the character that's less Asgardian prince and more Midgardian businessman. A stewardess comes up to him and he passes her a note. She thinks this is a flirtatious movie until he reveals that he has a bomb, and threatens the plane. The stewardess brings him a bag of cash, and he jumps out of the plane with it, before being whisked away by Heimdall through the Bifrost.

For some viewers, this might have just seemed like a fun gag, and a scene that simply shows Loki getting up to some hijinks after losing a bet with his brother. Others may have heard Mobius refer to Loki as D.B. Cooper and clued into what the scene was referencing, especially if they are fans of true crime. D.B. Cooper was a real person, and the story surrounding him that was shown in the episode is true, minus him being the God of Mischief.

In 1971, an unidentified man who was traveling under the alias Dan Cooper (which later became D.B. Cooper in the zeitgeist because of a news miscommunication) boarded and hijacked a plane traveling from Portland to Seattle. He was described as a man in his mid-40s, wearing a suit with a black tie and white shirt - essentially resembling every other businessman who routinely flew. Shortly after the plane took off, Cooper handed the stewardess a note, which she at first assumed was the man's phone number, and dropped into her purse, similarly to what happens in the Loki episode. Cooper then leaned over to her and whispered, "Miss, you'd better look at that note. I have a bomb."

Cooper showed the stewardess the contents of his briefcase, which contained eight red cylinders (the aforementioned bomb), and demanded $200,000, four parachutes, and a fuel truck standing by in Seattle to refuel the plane when they landed. The stewardess informed the pilot of what was happening and came back to find Cooper wearing dark sunglasses. He was never nervous or violent, the crew described that he was actually quite polite and calm. Once the plane landed in Seattle, a cash-filled knapsack and parachutes were delivered to Cooper, and he allowed the passengers and all except one flight attendant to leave the plane.

The plane then took off again, and Cooper told the remaining crew to go into the cockpit and stay there. This was the last they saw of him, as he jumped out of the plane once he was alone. A manhunt for Cooper was ordered, but he was never found. Despite a 45-year-long FBI investigation, the true identity of D.B. Cooper was never discovered, and the case remains the only unsolved instance of air piracy in commercial aviation history. Some of the ransom money was discovered in 1980, and the only other pieces of evidence that were recovered were a black clip-on tie, a mother-of-pearl tie clip, and eight Raleigh cigarette butts. Expert opinion states that Cooper likely did not survive the fall, but a solid conclusion about Cooper's real identity and fate has never been reached.

Until Loki, that is. Obviously, the show isn't trying to suggest that the answer to the mystery of D.B. Cooper is that it was Loki all along, but the scene is a fun nod to a well-known true crime story in American culture. It really does seem like the sort of thing Loki would do, and it's clever because the Bifrost is the perfect explanation for why D.B. Cooper disappeared without a trace. This scene is an example of the ways in which Loki can play with time travel and inserting a character into real historical events, and it would be really fun to see more scenes like this from the show in the future.
