The agency convinced him for nearly seven billion reasons.
You remember that time when Elon Musk appeared on the show The experience of Joe Rogan smoking grass by accident? Well, NASA learned about it and obviously they are not happy at all.
While the space agency has nothing against the use of legal drugs; seems to care about how it can affect the security of its operations, which one of its main contractors encourages the consumption of substances that change the senses.
It's not that Elon Mash will climb a rocket after he smokes marijuana. But your employees do. So, Jim Briden, a NASA administrator spoke on this topic; and stressed that Masha will not do it again in public:
I will tell you that (his behavior) was not useful and that he did not inspire confidence; and the leaders of these organizations should use this as an example of what to do. Especially when they will lead an organization that will open US astronauts in space.
I will tell you that he is committed to security as anyone; and he understands that it is not appropriate behavior, and he will not see him again.
Bridgestone said we will no longer see Elon Mask drinking alcohol or smoking in public. All while your company SpaceX and Boeing they co-operate in the project to achieve civilian flights in space.
All this together constitutes a contract for US $ 6,800 million. So anyone in the situation of Mask would surrender.
