SpaceX announced the plan for cross-world rocket flights cheaper than a business class ticket in 2018, by 2028, and Musk doubled down on the timeframe in an interview in 2020. Boom doesnt have a chance of earning back its investment if it will only be able to operate for a few years before Musk comes through on his aggressive timeline. Passengers will need to be fitted for spacesuits and there is no launch abort system.
Musk’s service will never fly, it’s pure fantasy. There’s no way that governments are going to allow an ICBM through their airspace just because some businessman is willing to risk his life to get to a meeting on time. To say nothing of the environmental costs.
