Behind the scenes of Boom Supersonic - The world's fastest jet

The world's fastest jet – that can get you from Sydney to Los Angeles in just over six hours – has received $43million in funding.
Boom Supersonic's XB-1 – dubbed the 'baby boom' - has been backed by a group of tech bosses, engineers and astronauts – including Virgin boss Richard Branson.
It's a technically representative version one-third to scale of the Boom Airliner that is set to be faster than Concorde – and cost more than $262million to build.Around 500 routes fit the aircraft's route, which when complete, the jet could take you from Tokyo to San Francisco (more than 8,000km) in just five hours.
You could also make a trip from London to New York and back in a day with a flight time of 3 hours and 15 minutes.
The jet will fly at around 60,000 feet, higher than any other aircraft before it, and break the sound barrier, but passengers won't notice it.
The design is quieter and 30 per cent more efficient than Concorde was – with the interior split into two single-seat rows so every passenger has a window and aisle seat.
However, fares will be similar to the cost of business class seats on major airlines.
When launched, the Boom Airliner's 45 seats are expected to cost $6,600.
But chief executive Blake Scholl says budget tickets could also be a possibility for the passenger jet, which could take to the skies by the early 2020s.
'Now we have all the pieces we need – technology, suppliers and capital – to go out and make some history and set some speed records,' he said last week.
