User blog comment:Halomasterjk/Skyrim DLC Rumors: Dragon Riding?/@comment-5280592-20121020220432

I'd just be the first to say that riding dragons doesn't break lore, just your chances of survivability. Flying several (whatever measure TES uses) in the sky on a dragon is unsafe no matter how you think about it. Anything from riding like a horse to aerial combat would likely throw you off the biology-defying-monstrosity and you would splatter into several chunks of carbon. It's most likely that you take the dragon to get to the island.

May I ask how one mounts dragons? They have spines all over and smooth scales. If you hold the spines you could slip on the scales and get impaled in midair.
