  In July 2018, Musk arranged for his employees to build a mini-submarine to assist the rescue of children stuck in a flooded cavern in Thailand. Richard Stanton, leader of the international rescue diving team, encouraged Musk to facilitate the construction of the vehicle as a backup in case flooding worsened. However, Stanton later concluded that the mini-submarine would not work and said that Musk's involvement "distracted from the rescue effort". Engineers at SpaceX and The Boring Company built the mini-submarine from a Falcon 9 liquid oxygen transfer tube in eight hours and personally delivered it to Thailand. Thai authorities ultimately declined to use the submarine, stating that it wasn't practical for the rescue mission.
