Flight HA446 of Hawaiian Airlines was scheduled to take off on the night of December 31 from Auckland, New Zealand. But a ten-minute delay in departure meant the flight finally took off on 1st January 2018.
Surprisingly, when it landed in Honolulu, 8 hours later, it was still December 31 2017.
It's not so complicated and apparently very common.
That does sound like Lost. Glad I'm not on that flight.— Greg Bussmann (@GregBussmann) December 31, 2017
Gotta wonder if the crew ran 10 extra minutes of diagnostic checks to make this happen.— Matt DeCample (@DeCample) December 31, 2017
Thanks to the occurrence, the passengers would have celebrated New Year's twice.
Flight HA446 wasn't the only flight that time-travelled from 2018 to 2017. Six other flights from Taipei took off in 2018 and landed in 2017 when they arrived in North America.
