In no particular order...

1. Communication between Bosch and the SC Rephaim.
2. "DIVE! DIVE! DIVE! HIT YOUR BURNERS PILOT!"
3. The entire Transcend campaign.
4. "A SHIVAN CAIN CLASS CRUISER JUST JUMPED IN! IT'S THE TARANIS!"
5. Any mission in a dark nebula.
6. Any mission in an electrified nebula.
7. Any mission in a nebula without substantial fighter/bomber cover and a cap ship to hold my hand.
8. GTXG Gorgon Canon

The command briefing before Lion at the Door where you first hear brief4. The moment that music starts rolling, you just know something is up, and that it's not gonna be good.

[Dave2040]

The Mission with the Actium and the Lysander.

In the first part of the mission you and the two Deimos class corvettes kick some Shivan asses, but then you could see someting big in the Nebula.
OMGWTF BEAMZ!!!

[Solatar]

Pandora's Box in Fs1, when the Shivan fighters jump in and start attacking you while you're scanning stuff. You know you're only going to leave one of two ways, and scanning the cargo starts to look like a better plan.

[Goober5000]

"Oh my God!  It's the Lucifer!"

Also, mission 6 in Silent Threat: Reborn is pretty scary.

 Mission 6-- can you refresh me on that one please?

[Sandwich]

Somebody remind me to get myself a USB joystick so I can (re)start playing FS2 again, m'kay?

[ToecrusherHammerjaw]

Scariest one was the moment I heard "Target exceeds superdestroyer specifications." 

LLivingLarge, what's the GTXG Gorgon cannon?

[Taristin]

I Call Bull**** till i can see some proof!

[CP5670]

Definitely the "Dive! Dive! Dive!" message. That one really caught me off guard the first time I played the game, as I was busy thinking about how cool it would be to fly a Mara.

Just play with a keyboard like I do.

The nightmare sequence in Derelict was very well-done, as was any sequence in the Transcendant's nebula. Actually, the first time I had ever been generally freaked out or scared by a FS campaign was in Sync, right after the first jump. The sheer calm of the arrival really made a first impression: something felt wrong, and there was something wrong, and then nebula mission that followed really sealed it. Pretty much any slow and/or nebula mission by Ransom Arceihn is scary enough.

I'll agree with Pandora's Box being good, but the entire Altair series of missions really did it in for me, with the Lucifer arriving and pouring out fighters on the transports, then to the understanding that you and your squad are pretty much alone behind enemy lines.

Of course, nothing can beat just the sheer atmosphere of FS1 in general. The whole game just had an eerie tone to it. Listen to the Monolith track if you don't believe me.

[NGTM-1R]

Derelict, when you hear the Narlythotep (probably didn't spell that right...) transmit for the first time. You get the mounting sense something is wrong the whole mission, and then this Lucy starts speaking Shivan and you're like "Oh HELL."

[phreak]

1) Any of the nebula missions in transcend.
2) Any of the nebula missions in transcend.
3) Any of the nebula missions in transcend.
4) Any of the nebula missions in transcend.
5) Any of the nebula missions in transcend.
6) Warping in right in front of a Sath in ITLD
7) Lucy waking up in Derelict
8) Whenever hostiles warp right on top of me when im in a bomber.

Fair enough.  Not sure how long it'll take, though.

I actually designed that mission with the express purpose of being as scary as possible. I think Ransom Arceihn may have one-upped me though.

[karajorma]

There's a mission in MindGames that made me nervous as hell even though it was me who designed it (Miburo did FRED it though).

Lion's Den and Transcend win the award out of missions others might have tried.

[Nuclear1]

I think Ransom Arceihn may have one-upped me though.

Ransom Arceihn is to mission design as Blaise Russel is to campaign making. They both have the ability to do something far better than most of us here, be it by making an utterly terrifying campaign or by pumping out a bunch of campaigns.

I'm still waiting for ST:R nevertheless. Spook Moments x The Other Spooks = Spook^2.

[Carl]

First mission on the other side of the nebula. The binary star system, the 3rd knossos, the dozens of sathanii coming in, it all just gives you a "we are in so deep" feeling.

[Starks]

Transcend was just one ****ing huge screamer...

You know it's coming... You don't know when though.

[Alpha0]

I think Transcend will have to get my vote, too. Scariest moment:

Spoiler:

When you hear the Transcend trying to communicate with you and says, amongst static, something like "Help me...", *silently* "Help me...", *suddenly, VERY loudly, heavy background static* "PLEASE!....".

Haven't jumped  so high before while playing a game. Not even Dive³ managed to scare me that much.
