While traveling during his ultimate, is Nocturne targetable by friends or foes?

Question

After Nocturne uses Paranoia and subsequently launches himself at a target, can he be targeted by either friends or foes?

For instance, it's been shown that Quicksilver Sash can remove the vision debuff. Could you remove the debuff and then stun him in-flight (removing the debuff so you could actually see him arriving)?

The answer for this should inform on what happens when a friendly Shen ports to a mid-flight Nocturne. The fact Shen can even attempt to port a mid-flight Nocturne leads me to believe he's more-or-less targetable, but I haven't seen any definitive evidence.

Answer 1

Nocturne is immune to Crowd Control effects when he jumps. When the enemy tries to CC Nocturne in-flight (even without targeting him, such as using Janna's Howling Gale), the message "Cannot Be Disabled" will appear above him.

Shen can teleport to an in-flight Nocturne because Shen's shield and ult are not CC.

EDIT: Michel found this great Youtube clip that shows this in action.

Conceivably, Nocturne could be targeted by an auto-attack in-flight. But since the enemy team usually doesn't have any vision and he moves quickly out of auto-attack range even if there is vision, this rarely happens.

If you watch Nocturne's health in the Youtube clip carefully, you'll notice that even though he gets hit by Amumu's and Galio's ults, he doesn't take any damage. This suggests (doesn't prove) that he is immune to damage during his jump. It'd be great if somebody could test this and post the results.
