Voyager 1 bravely going where no machine has gone before. And phoning home the details.
Wrong!
It was Voyager II that left our solar system first. Read all about it here.
I was part of ARIA (tail number 329) at 31,000 ft covering the launch and orbit out of Perth, Australia. That was on August 20, 1977. My story is at the bottom of the link about Voyager II.
Thanks for bringing up the memories and remember Voyager II was Number 1!!!
Cheers!
