Can I use Unity3D in Flash?

Can I use Unity3D in Flash?
I know Unity3D does not support for Flash anymore.
Recently I’m trying to bring Unity3D in Flash.
But I’m stuck now. so I would like to ask about it can be done.

any comment will be very grateful. Thanks!

Development environment

Tool : Flash CC
Language : ActionScript 3.0
SDK : Adobe AIR 17
Platform : Windows OS

No. Unity doesn’t support flash builds, and hasn’t for some time. WebGL and web player are the supported web platforms.
