Auckland:  Passengers on Hawaiian Airlines’s flight 446 experienced a bit of time travel to start off their New Year.

The flight, which travelled between Auckland, New Zealand and Honolulu, Hawaii, was scheduled to depart at 11.55 pm on Sunday, Dec. 31, 2017. However, because of a 10-minute delay, the flight didn’t end up taking off until 12.05 am on Monday, Jan. 1, 2018.

Due to the time difference between New Zealand and Hawaii — the former is 23 hours ahead of the latter — passengers ended up landing at 10.16 am, back on Dec.31 in 2017.

In between New Zealand and Hawaii is the international date line, which explains the hefty time difference between the two locales. Sam Sweeney, a transportation reporter for Washington, DC, station WJLA, was the first to notice the sci-fi-esque take-off and landing times of the flight.

Once Sweeney tweeted out his discovery, people took notice — and had quite a few questions. While others couldn’t help but make plenty of pop culture jokes, from a confused Dr. Phil to Lost to Back to the Future.
