No, I was in creative mode. Or at least should have been. Also, when viewing my character, I was fully visable, unlike when in spectator mode where I'd only be able to see a ghost version of my head.
And as I said before, I floated down, not fell. If I was in spectator mode, I shouldn't have been able to double tap space to exit out of flying.
Alright. Will do so if it occures again.
