Anyone who grew up watching Back to the Future, Doctor Who or even the Bill & Ted movies will be familiar with the concept of time travel. Paradoxes and technical difficulties, it looks like good wholesome fun.
So it's pretty exciting to learn that one aeroplane has just managed to travel backwards in time.
Well ok, 'sort of' is the key phrase here - so probably best not to start planning a trip to warn Past You about all the mistakes that got in the way of your wildest dreams.
However, on Sunday Flightradar24 tweeted the flight path of Hawaiian Airlines flight HA446, which showed the plane having taken off from Auckland in New Zealand in the year 2018, before landing in Honolulu, Hawaii, which still had yet to ring in the New Year.
"Time travel is possible!" Flightradar24 said. "Flight #HA446 just took off from New Zealand in 2018 and will land in Hawaii back in 2017!"
Yes, it's more a result of time zone quirks than a fantastical breakthrough in science and technology, but pretty exciting for everyone involved, you'd imagine.
Auckland is 23 hours ahead of Honolulu, with New Zealand and Hawaii sitting either side of the International Date Line.
Funnily enough, the phenomenon was only able to occur because of a ten-minute delay to the flight departure. On the plus side, that's two opportunities for cabin crew and passengers to celebrate the changing of the calendar, so good news for any fans of the sesh on board the flight.
Social media was initially baffled at the announcement, as you might expect:
But some passengers were on hand to provide proof to non-believers:
Not quite as exciting as a Delorean flitting between 1985, 1955, 2015 and 1885, admittedly, but still pretty cool - or at the very least, quite interesting.
Now if someone could just arrange for me to travel back to last night so I could prevent this New Year's Day hangover, that'd be great.
