A European jet startup wants to fly people from New York to London in 90 minutes using a hypersonic jet. See what the plane could look like.

• European startup Destinus is designing a series of ultra-speedy aircraft capable of reaching Mach 5.
• Liquid hydrogen combined with jet and rocket engines will allow the plane to cruise at 108,000 feet.
• Models “Destinus S” and “Destinus L” could connect cities like New York and London in just 90 minutes.

The world has not seen a supersonic aircraft since the demise of the Concorde in 2003.

The legendary plane connected New York and London in as little as three and a half hours, but several factors including its costly fuel-hungry engines made the Concorde difficult to sustain.

Nevertheless, that hasn’t stopped several aerospace startups from coming up with new and environmentally friendly ideas for a super-speedy planes. One of the most well-known is Colorado-based Boom Supersonic, which is making progress on its Overture jet. US carriers United Airlines and American Airlines have already placed orders.

However, there are a few other companies hoping to create an even faster aircraft that can outrun the Overture and the Concorde, including European aircraft manufacturing startup Destinus.

Insider spoke with the Destinus team at the Paris Air Show in June to learn more about its hydrogen-powered hypersonic jet — take a look.
