SpaceX, on Friday, continued to prepare for the fifth test flight of its Starship launch vehicle despite rising tensions with the Federal Aviation Administration (FAA), the federal agency responsible for greenlighting launches.

SpaceX has voiced its distaste before with waiting on the Federal Aviation Administration to grant licenses for previous launch attempts of the largest, most powerful flying machine ever built.
