Unfortunately, the jet isn't guaranteed, and it's possible that high operating costs will stunt the plan. A spokesman for Airbus said "Airbus Group and its divisions apply for hundreds of patents every year in order to protect intellectual property... These patents are often based on R&D concepts and ideas in a very nascent stage of conceptualisation, and not every patent progresses to becoming a fully realised technology or product."
A similar proposal in 2011 assumed 30-40 years for the plane to be in working condition, but, The Guardian repots, the patent is meant to "put down a marker for technology that could be useful in other developments."
The hypersonic jet would also be able to get from LA to Tokyo in three hours, as previously prophesied by Iggy Azalea.
