When playing a game today I ran into the situation where my Night Scythe lost it's weapon and since you can't embark on it with the current rules it became useless. The thought hit me that perhaps I could just crash and burn into my opponent. The Flier rule basically states that if you move under 18" you are wrecked. Of course you can't place the model on top of another, it has to stay 1" from your opponent, but can then scatter.

So can you actually do this voluntarily? I haven't been able to find a rule that says you can't nor have I found one that says you can.
