Newby here. Yeah, I just realized I spelled his name wrong. I apologize if this has already been addressed but I looked briefly and could not find an answer. On "Come fly with me" I did everything required, however upon returning with the parts for Chris Haversam he is not there. I can see him on the mini-map so to speak, (he is at the entrance of the in the room with the bulletproof glass overlooking the rocket). However he isn't in the actual room? Is this normal and what do I do if anything to find him. It seems like a game-glitch so to speak. Prior to this happening; all of the guys down below the glass in the spacesuits showed up as (yellow) friendlies but there was one guy below dressed like a mercenary who appeared (red) on my indicator. He then shot at me through the bulletproof glass. Could this have affected the mission causing Chris to glitch? Looking forward to some answers. I would really like to complete this mission properly. Thanks.

The guy dressed as a Merc, was he a Ghoul? You are supposed to meet him and optionally help him during this quest.

Anyway, as for Missing Chris, if you have not gotten the parts for him (or given them to him yet) then try this. Reboot your system and or clear any cache, then load the game up again and see if he pops in the cell.

I have had NPCs go awol on me before, one time I had to use TCL in the console, another I just left and came back and when the cell rendered again, there they were.

If nothing else, you do have a save from just before you started this, so you can go back, right?
