The Mission of Alien Goo isn't needed to unlocking jetpack right?
Just make sure to go into area 69 and u will see jetpack around but maybe any players can take it

No, you should get the thing that look like a bag the one I picked in the video 1:50 then give it to the professor NPC right near the jetpack like I did in 5:20
