World's Longest

For a drone company that just broke cover in May, SiFly has certainly gone from strength to strength in 2025. Its latest achievement came on Orville Wright's birthday, when the company's Q12 drone soared into the most famous record book in the world.

The Italian government has given the green light to an incredibly ambitious plan to connect Sicily and mainland Italy with the world's longest suspension bridge. Measuring a length of 2.24 miles, the project is expected to be completed in 2032.

This year has produced a stunning amount of ambitious architecture. From a futuristic skyscraper, to the plan for the world's tallest timber tower, here's our pick of the top 10 most ambitious architecture projects of 2024.

Peter Salzmann has already pushed wingsuiting to a new level via electric propulsion. Now he's back, unplugging the power with a dramatic new foil system designed to push man closer to the gravity-flaunting freedom of bird kind.

Hybrids could have almost as much potential in the air as they do on the ground. Ampaire says the clever first-gen hybrid powertrain in its Electric Eel demonstrator cuts fuel consumption by 50-70%, and it's just logged a world record for endurance.

Electric touring is officially on the menu ... Sort of. Evoke has built its 6061-GT electric motorcycle around the biggest battery pack ever offered in a production bike: a staggering 30-kWh monster offering more than 600 km (370 miles) of range.

If you want an electric boat to get very far, you either need huge amounts of battery, or you need to lift your hull out of the water on a hydrofoil system to cut down energy-sapping drag. The SpiritBARTech35EF does both, for record-smashing range.

It’s no secret that sauropods had really long necks, but now paleontologists claim to have identified the species that takes the crown. According to the team, Mamenchisaurus has the longest neck of any known animal ever, measuring 50 ft (over 15 m).

Autoflight has debuted its 4th-gen full-size eVTOL air taxi prototype with a bang, celebrating the longest-ever recorded flight of an electric VTOL aircraft. Prosperity flew 250.64 km on a single charge, relegating Joby Aviation to second place.

We will never complain about finding a parking spot again. The "American Dream," now stretches to more than 100 ft, seats more than 75 people, and has its own pool, diving board, jacuzzi, bathtub and mini-golf course. Oh, and a helipad.

Those nervous of heights should definitely steer clear of the newly completed 516 Arouca bridge. As its name suggests, it spans a total of length 516 m and is hailed as the world's longest pedestrian suspension bridge by Portuguese officials.

With perhaps a few exceptions, battery-electric multicopter drones typically can't fly for longer than about 30 minutes. Such is not the case, however, with their hybrid counterparts – one of which recently broke its own endurance record.
