Following the catastrophe of Flight 5342, President Trump named an interim replacement for the vacant position of FAA administrator after the SpaceX founder chased out predecessor Mike Whitaker.

Elon Musk had sharp words for a private-sector partnership touted this week by the Trump administration to hasten the development of artificial intelligence infrastructure. “They don’t actually have the money,” Musk said of two of the participants in the $500 billion initiative, OpenAI and SoftBank, on his social media site X.

The leader of the Federal Aviation Administration stepped down from his position mere months after billionaire Elon Musk demanded that he do so, meaning that the FAA is missing a chief in the aftermath of the worst aviation disaster in the US in years.
