Sad the holidays are nearly over?
The future of transport
Airbus announced on November 30 that it’s developing a hydrogen-powered fuel cell engine that it plans to test on an A380, the world’s biggest-ever passenger plane. Test flights are planned for 2026.
And in other transport innovations, the XPeng flying car completed its first public test flight in Dubai in October. The all-electric, two-passenger vehicle takes off vertically without need for a runway and so is suited to built-up urban areas.
Down at ground level, lightweight microcars might be the future of city driving, as countries around the world take steps to clear their streets of heavy traffic and pollution.

Spotlight on Hawaii

Former flight attendant Gwendolyn Bruhn, 94, flew with Hawaiian Airlines back in the 1940s, years before Hawaii became a US state. Here are her memories of attending to stars including Jimmy Stewart and the swimmer Esther Williams.
Hawaii has long been one of Japan’s favorite vacation destinations. The reason for its enduring appeal is something the Japanese call “iyashi,” meaning “healing” or “comfort.” Here’s the story of that love affair.
Spotlight on Saudi Arabia
Drone footage shot in the Saudi desert has revealed a huge, fish-shaped rock emerging from the sands. Photographer Khaled Al Enazi captured the unique aerial perspective.
And in other “Saudi things that look like marine life but aren’t,” a design company is hoping to make an enormous $8 billion turtle-shaped boat that could become the largest floating structure ever built.
CNN’s Richard Quest visited Saudi Arabia earlier this year: Here’s what he discovered.

Fasten your seat belts
Each week we highlight a traveler who’s had a brush with the law, and this time it’s the turn of Odell Beckham Jr. The NFL star was removed from a Miami flight on November 27 after refusing to comply with safety protocol, police said.
Beckham Jr. took no chances when he set out on tour on December 1. He posted an Instagram story from a private jet, saying “not today” and “back to the regular.”
