Of course, this is what I did.
Last week, I went to IF with my HS on cooldown. There's a trick where if you log out while in an arena skirmish, you return to your hometown (alliance side dalaran inn, in this case)
Order of events which happened:
-Entered blade's edge arena
-Logged off as soon as I entered (there's no 20 second wait in arena for some reason)
-Tried to log in asap but got disconnected at the loading screen for some reason (maybe due to continuous alt tabbing)
-I logged in on my second attempt, but I was floating in midair and died from the fall (presumeably I was ported to the dalaran inn, but my client side zone was still blade's edge arena?)
-When I released, I was given a spectral flying mount (as I was in crystalsong forest), which I used to see the scenary which the arena could hold-ie I could only go as far as seeing areas close to dalaran, like the VIolet Hold door, crusader's pinnacle, a random ziggurat in icecrown.
