The head of SpaceX company Ilon Mask provided a mini-submarine for participation in the rescue operation, formed near the cave of Khao Luang in Thailand. However, the equipment presented was recognized as too technologically complex and advanced for use in the designated procedure, the Khaosod newspaper reported. Mask arrived in Chiang Rai province on Monday evening to provide the necessary assistance in the rescue of teenagers who have been locked in the dungeon for more than two weeks. In the use of the governor was handed mini-submarine "Forest Boar" for later use if necessary. It is worth noting that the ship is named after the injured football team and their coach.
