The only animation available to archers is shooting a dragon out of the sky but that is damn hard due to how fast they fly, and their erratic patterns. Did I mention how fast they fly? But yeah its pretty damn difficult have any of you done it?

They always crash land before then.

Ive shot a few out the sky but not with bows and arrows but with the lighting storm spell.

few times with thunderbolt and storm call.

im plan to take aleast one down by only using telekinesis and sweetrolls now that i know you can hurt people with telekinesis

I've done it once, but only because it had a pattern of attack caused by the terrain. It had only one way it could attack.

I did but they never fall and decided to land first before the last breath.

I did it few times on my mage using thunderbolt, but it causes so much bug if dragon dies in air so it was kinda meh.

So that crash landing like in the trailer isn't in game?

Yes it is, but the only time I've seen it is on a plot dragon.

once but id alreadt hurt it when perching on a dragon wall, it was bad ass to have it crash land with one more well placed arrow and have it smash right into the dragon wall, with limited spazing out, i might add, which is nice.

Once my dragons get to about a third health, they don't fly away again. And I can't three shot a dragon.

I've tried but I don't think I've every hit it when it was flying around. I did hit when it's flying but hovering stationary and relatively close. Sometimes it just does that, and it does hovers when it's using it's destruction breath on someone or something (like a town).

But when it's moving in the air no. Related, I've had a few times when the dragon appears, I even get the dragon attack music, but then it never gets close to my character. It just flies overhead or far away and never seems to land or attack my character.

The crash landing is in the game, however sometimes it doesn't show up. The trick is to use a very powerful and enchanted bow with very powerful arrows (daedric for me) and a little luck. If you have a good sneak skill, you can get "hidden" using invis while the dragon is circling you for some extra umph.
As for the ways I've killed a dragon:
1. Beat it to death with a mace because it refused to take off.
2. Epic battle involving shouts, bows, and mace with a shield.
3. Naked with only a one handed weapon.
4. Fisticuffs. *took a LONG time because the dragon didn't want to land that often*
5. Jumping on it's head and cutting it to death with a pick-ax.
6. Using only shouts and healing spells.
7. Fisticuffs naked. *even longer*
8. Using an undead army. *well... squad...*
9. Having my horse kick it to death and laughing maniacally.
10. Throwing cheese at it with telekinesis.
11. Same thing but with troll and human skulls.
12. Same thing but with random potion ingredients.

I swear, if I had a Roxio I would be able to make a machinima. "How to hunt and humiliate a dragon".
