Did you know that Space X was originally a brand name for late 1960's & early 1970's a line off toy space exploration vehicles & spaceships marketed by Triang??
I still have a couple of Triang Space X models around the house.
If Triang (the world's biggest global toy manufacturer in the 1960's) hadn't have folded in 1971, I'm sure that they'd be suing Elon Musk over the use of the Space X brand name.
