Musk's offer of mini submarines was rejected as they were far too big to fit through the gaps and didn't even have provision for breathing apparatus!
Seems like it was just a publicity stunt. Fancy that!
And ruined the life and reputation of one of the rescuers who had the gall to criticise the design of the sub.
He had a young looking Thai girlfriend/Wife (?) who was actually 40 years old.
What a vile person.
