Decent, if you can fit the aged guy with the backstory. It's not impossible but it's rare to see a 60 year old man on a camping trip with 20ish year olds. 

We need to polish some strengths/weaknesses, namely : 
bar fights - can this be brawling instead? bar fights seems so specific to bars haha
scaring random strangers - I suggest this to be intimidation instead, but this would do if you want

always blames aliens - I have no idea how to translate this to a weakness haha. It must be a weakness, I just can't see how this is one. Perhaps you can elaborate? Remember I'm gonna use your weaknesses to help me decide on outcomes.

drinks too much - alcoholic maybe? Although this is fine, but he's never gonna be sober

Other than that, it's fine. For the backpack, I have no idea what to do with it so I'll allow it haha!

When you update the sheet, we can maybe start, unless you guys wanna wait for another.

EDIT: Just noticed the backstory. It's alright, I guess. As long as you can link him to the other guys! (If he got on the wrong plane, why did he tag along with them?) Other than that, and the updates above, you're good.
