And before foreigners get too smug, the UK was only two years ahead of the US, criminalizing rape within marriage in 1991. You may recognize that as the year Bill & Ted's Bogus Journey came out. So yeah, criminalized marital rape in the United Kingdom is exactly as old as Bill & Ted's Bogus Journey.
Airport Security Didn't Exist Until The 1970s

Although commercial flight began in 1920, it would be decades before anyone would come up airline security. Before that time, people apparently assumed that crime ceased to exist once you were five miles above the Earth, or that commercial aircraft were under the jurisdiction of Zeus, King of Olympus.

Literally nothing was there to prevent sky murder, sky bestiality, etc.
Finally, after four US flights were hijacked in as many months(!), President John F. Kennedy instituted the air marshal program, which put officers on certain flights and required that all planes begin locking their cockpit doors, because for some reason this wasn't something they already did ("But what if a passenger has a question?"). But this wasn't quite enough -- by 1972, another 72 hijackings had occurred. That is not a misprint. Seventy-two. Air travelers in the early '70s essentially had an almost equal chance of reaching their destination as having their flight featured in a TV movie.
So in 1974, metal detectors were introduced into airports to catch anyone trying to sneak weapons onto a flight, since the honor system clearly wasn't working. Even then, airlines still had a blind spot when it came to staff. In 1987, an ex-employee of US Airways named David Burke managed to board a plane with a gun, even though he'd been fired from the company months earlier, because he still had his company pass and nobody thought it was necessary to check the bags of an airline employee. That plane crashed, and although the investigation was inconclusive, the sound of gunfire on the black box and a suicide note written by Burke on the outside of an air sickness bag led many to believe that he might have had something to do with it.
