This air shaft may work to our advantage.

We've gotta reroute all these ducts.

It's using the air shafts. We don't know that...

Disappeared into one of the cooling ducts.

There's an electrical service duct right behind your drummer's riser.

Okay, jack, there's an airduct leading off that unit do you see it?

No question. It's using the air ducts to move around.

Will you listen to me?

I wish I could fix warp engines... with duct tape and a pocketknife.

A very unique engine it's round, it's small, it's vibration free.

He inspected the air conditioning ducts last year, computer relays the preceding year.

That temperature is controlled by the air conditioning duct, 30 feet above the floor.

We can't fix it out here anyway and we need to reroute a couple of ducts.

It will vent nothing but clean, odorless steam just as the laundry does and through the very same stacks.

We can also contrive the way to control the condition of the air inside a building.

They commissioned a group of their best scientists to investigate, and what they found was that all these tape drives were located near ventilation ducts.

So they began working on this high temperature reactor, and here was their notion. This reactor was going to produce this high temperature heat.

So we repair the barricades at these two intersections, and weld plate steel over these ducts here, here and here.
