Anaesthetist Richard Harris, who did the final medical checks of the 12 trapped boys and their coach, was among the divers who successfully ended on Tuesday a mission that had gripped the attention of the world.
The incredible rescue has been deemed a miracle by many, but the operation wasn't without tragedy.
The eight boys brought out by divers over the previous two days are in "high spirits", a senior health official said. It is now unclear whether Musk or his technology will be used in the rescue efforts, but Musk confirmed via tweet that the submarine is in Thailand and ready to be used if needed.
His Highness Sheikh Mohamed bin Zayed Al Nahyan, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces said that he was glad to hear that the rescue operations were successful.
All 12 boys trapped underground in Thailand have been rescued following the "largest, most complex cave rescue in history".
A health official said the boys lost an average of 4.4 lbs during their ordeal but are generally in good condition and have shown no signs of stress.
Experts warned that drinking contaminated water or otherwise being exposed to bird or bat droppings in the cave could lead to risky infections. The diver who spoke to AFP said the boys were "groggy" but "breathing" when he helped to pull them out, while the BBC reported that according to divers, the boys were "heavily sedated to avoid anxiety".
"The first day we spent 11 hours, yesterday we spent nine hours, we hope we can do it [today] quicker or at least as quick as yesterday".
"My wife actually grew up with the Thai Navy SEAL that died in the cave".
Rescuers brought out the last five on stretchers, one by one over the course of Tuesday, and they were taken by helicopter to hospital.
They were found by a pair of British divers more than a week later. However, doctors later relented after some of the boys asked for bread with chocolate topping.
The first of the rescued boys were due to be reunited with their parents on Wednesday provided they wear protective suits as medics work to rule out any infections.
Jesada said they were uncertain what type of infections the boys could face "because we have never experienced this kind of issue from a deep cave".
The perilous mission saw the boys having to use scuba masks as they were led through the narrow tunnels to safety. Elon Musk recently pledged his team's help in rescuing the group. Mini-sub is ready if needed.
