Well, you're right on several levels, but I think it was a trick question. Pointing straight up, you definitely wouldn't see them because they're coherent light, and without something to diffuse the light or be reflected off of, you won't see anything. (Think of a laser pointer. You don't see the beam in clear air, only the point when it impacts the wall/screen/cat/whatever.)
I am so slow sometimes ...... you know I think we could save the US taxpayer alot of money here!
We could just set up a row of deckchairs alongside the LIGO's. Equal numbers along each arm for greater sensitivity. Oh, and that would be deckchairs with cupholders. Tell the scientists to go home for the weekend. Get a volunteer group to watch the lasers. Of course you'd have to supply them with beer and pizza. Now if, after a while, enough of them think that a gravity wave has passed by - then we'll call it a detection!
Any volunteers to form a quorum? :-)
Cheers, Mike.
Would the results of the experiment be compromised if one of the observers, say me, used Strongbow cider rather than beer? Or would that relegate me to a purely supervisor capacity?

Eh... could go either way. Gravity waves are a tricky thing...
Here's an absorbing question for you. If LIGO could aim its lasers straight up, in the night sky, how bright and what color would they be?
Well the input laser strength is 10W, not much, but it's wavelength is 1064nm. That's in the infrared. The human eye is quoted as seeing as around 400nm to 700nm, as low as 380 for werewolves and maybe 780 for vampires :-) ( with peak sensistivity at 555nm )
Alas, we wouldnt see it!
Cheers, Mike.

No, not at all. All good science needs a control group or four... :-)
So, we're up to -
Hanford 4K SouthWest Arm Quorum ( H4SWAQ )
#1. Mike Hewson. (Hawaiian/Fosters)
#2. KSMarksPsych. (Pepperoni/Shiner)
#3. Michael Roycraft.
#4. John Hunt. ( Pepperoni/Pepsi)
#5. Raven. (?/Strongbow)
Amendment to specification: that would be deckchairs with cupholders, and optional mounting of trays for eating off, and night vision IR goggles, and a light sabre ( choice of colors? ).
Cheers, Mike.

Ok, that's .....

Yup pizza's the go,
Your choice of: Hawaiian, Capriciossa, The Lot .....
For the beer,
Your choice of: Fosters ( of course ), Bud, Heineken .....

Shall we do the Hanford 4km SouthWest arm?
Now you have to watch carefully so we don't miss any gravity waves!
Cheers, Mike.

#3. Michael Roycraft.
We'll knock up a spot for him with us.... :-)

Definitely the delux chairs. And if we could get some cushions that would be great too.
SW arm sounds great.
Can I have peperoni pizza and a Shiner (Texas beer)?

I'd like to volunteer too Mike.
Pizza with plenty of Pepperoni and make that Pepsi please 'cos I'm tee-total.
RE: RE: ::raises hand

Sounds like a real party getting started.
::passes the pizza and soda::
Now keep your eyes peeled. Those gravity waves can be hard to see sometimes.
Wait, what was that?

It was not a trick question. There are laser pointers specifically for astronomy purposes. Think green and more powerful.

Class IIIa lasers are limited to 5mw power so LIGO has enough power. I bet an infrared camera would see it.

Class IIIb lasers can go a lot higher.
