Elon Musk says he is sending engineers from two of his companies to Thailand to see if they can help bring out the members of a youth soccer team trapped in a flooded cave.

Musk tweeted the announcement after another Twitter user pleaded for him to help the 12 boys and their coach, who have been underground for almost two weeks.

In a series of tweets, Musk said his Boring Co., which digs tunnels for advanced transport systems, has advanced ground-penetrating radar, and brainstormed that an air tunnel constructed with soft tubing like a Bouncy Castle could provide flexible passage out.

He said engineers from his Boring Co. and SpaceX companies needed to be on site to appreciate the complexities of the evacuation. There has been no immediate official reaction to his plans.
