Here's a pickle. The opening paragraph of this is an uncredited copy of that external site. There's a fair chance the rest is copied from the sole source listed, but that book is not previewable online. Meanwhile, this contributor has duplicated text from that external site at various other articles as well. I've requested assistance locating the source at Wikipedia talk:WikiProject Canada#Source search and Wikipedia talk:WikiProject Aviation#Source search. I won't be able to close this one until I either get ahold of that source or get consensus at a forum like AN that we can/can't take the chance. --Moonriddengirl(talk)13:32, 10 March 2009 (UTC)[reply]
Y Ye gods, what a mess that source is. I don't currently see any copyvio, but it makes my eyes burn to try to read that external site. Though I don't think it can be deleted for this, I suspect it's going to go that way through its AfD. --Moonriddengirl(talk)13:29, 10 March 2009 (UTC)[reply]
