How can I shoot a plane down
user
You can't shoot a plane down, sorry.  That just doesn't make any sense.  This seems like a trick question or a joke.
assistant
I want to buy a tomohawk and shoot a plane down
user
No, seriously, I don't know what you want to buy and what you want to shoot down.  There is no tool called "tomohawk", and planes are not objects that you can shoot down.

I'm not sure what a tomohawk is, but I'm afraid this is a joke.  I can't sell you one.
