So in Trevor's missions he aids in a crash of a cargo plane into the Lost Sea. I though their would be a follow up mission to recover the cargo of that jet - but alas no such mission came up.
So after getting the money and the resources together. I decided to conduct an expedition into the Lost Sea to find the plane. I didn't know what to expect but what I found was pretty cool.
As far as I can tell, there is no other video of this that I"ve seen. I guess nobody went to look for it but me.
