(8:59) ATC: Northwest 11 85, uh, contact Cleveland Center again on 1 3 2 point 2 5, unfortunately they're going to have to put you in a hold for a little bit, the tower lost, uh, we just all control in the tower.
(9:10) NW1185: Bummer. Northwest 1185.
(9:31) ATC: ... Yeah, we're getting ready to close the tower. 3 right, position and hold
(10:53) ATC: Northwest 7 fifty, turn right heading 2-1-0, you're one of the last ones they're going to get in also...
(11:30) ATC: We're going...D T W tower is going to A T C zero. Uh, they were doing some work on mold and they did some spraying that is sickening people. So we're going to hold at all four sixes now and trying to determine what we'll be able to do as far as accepting after that. Alright?
(11:53) UNK1: So, is everyone going back to the center?
: Uh, the last guy told us you're going to evacuate the tower or something?
(12:00) UNK3: No, it's not weather, they're using some sort of chemical agent up there and people are puking blood up and passing out...
(12:09) ATC: Folks, [unintelligible] we're getting ready to get minimal personnel in the tower due to the fumes.
: ...aparently they're using some chemicals that aren't very conducive to breathing and they got up into the tower
: They can't open a window?
(12:42) NW753: Is everything OK
(12:43) ATC: Yeah, they sprayed something for mold and it appears to be the wrong chemical and people are getting sick and throwing up and stuff.
: [Laughing] Ummm, OK
(12:51) ATC: Put that on top of the de-icing and [????] it up for everyone else.
: Uhhhhh, what else can happen today?
(12:59) ATC: That's right.
: Wait, maybe I shouldn't say that.
(14:07) ATC: I'll try to get you out of here...we're in the process of evacuating the tower, so I'll try to get you out of here as soon as I can
[...bits I'm not transcribing...]
(19:09) ATC: Do it on the runway, please, we're getting ready to go to A T C zero on the tower, we've got five arrivals and then the field will be stopped...
... There's more, but this is all I'm going transcribe for now.
BTW, what is "ATC 0" and "hold at four sixes" mean?
