So you think that if you have 'fly' movement will allow you to end your turn over somebody's else miniature? I seriously doubt it.
but to allow you to end the movement on top of somebody is probably too much.
Why shouldn't a flyer end his turn over someone else's miniature?
If a person is running at 6 squares, twice per round, in a straight line for 5 rounds, we don't assume he runs 12, then stops and stands still til his next turn, then runs 12 and stops again, over and over. He just keeps running.
But, we have to put his figure somewhere, so after he runs his two moves of 6 and ends his turn, his figure stands in that spot until his next turn.
Same with flying.
That flying monster has to end a turn somewhere. You know, and I know, that it did not stop and hover, but we have game turns and its turn is over, so we put the figure somewhere on the battle mat and the figure sits there until the flyer's next turn to move.
Why can't that spot be directly over another figure? A halfling only occupies one square vertically. A human occupies two vertical squares. A giant might be 3 or even 4. What if that flying monster is 10 squares off the ground? or 100?
Just because the game surface is a 2 dimensional battle mat on a table, and your griffon miniature doesn't hover on its own, doesn't mean the griffon cannot end its turn 10 squares directly over someone else standing on the battlemat.
This does not mean the griffon is "on top of" the other figure. They're not grappling. There is no contact.
It is merely above the other figure. Directly above.

Ladders? Are we playing D&D or Snakes&Ladders?

Either ladder will be short (and then it doesn't matter) or if we are talking about surface-to-Underdark epic ladders, it probably makes more sense to cast the spells perpendicular to wall (so map instead of representing north/west/south/east will represent up/left-of-ladder/down/right-of-ladder and you get burst 1 on such map).
How short is short?
A 30' siege ladder with orcs climing up it to get into Helm's Deep is tall enough that the orcs at the bottom will be cooked by the burst, but the orcs at the top will be safe.
And in this case, it will definitely matter whether the mage put the spell on the ground (3 x 3 x 2) or 5' off the ground (3 x 3 x 3) or even if he put the spell at the top of the ladder to cook the top orcs so they fall on the bottom ones.

Yes, that would work, but I'm not tacking my battle mat onto a wall and pinning my minis to it.
But you don't need to turn the facing of the spell. It is 3 x 3 x 3 regardless of whether it gets cast near the ground or near a wall or ladder. And if it is cast adjacent to a surface (ground, wall, whatever), then part of the area of effect is blocked by that surface which causes the spell to have a reduced area (3 x 3 x 2).
