Ashley was not suggesting adding solid behavior to your airplane sprite, but that you turn it off on the wall that the plane is colliding with if you don't want it to bounce at that time.
In my example the ball goes through the walls when you left click (which turns off bounce off walls) only because the ball was placed in the layout before the walls. If you want it to go over the walls, just move the walls to the bottom of the z order. (Or you could put the ball on a layer above the wall layer.)
I updated the project so that it has the walls at the bottom. The ball flies right over the walls when you left click, and bounces off the walls when you right click.
Note that any changes you make to one bullet behavior you should make to the other bullet behavior. That is why I copied the angle of motion from one to the other when switching behaviors. That would also apply to speed.
Both objects aren't bullets, and we can't allow other objects but the plane pass so this wouldn't work.
The easiest solution is to adjust that parameter for the bullet behavior on the plane using the event sheet. You can adjust others, but not this one parameter unless I'm just missing it...
