He owned 3 planes.

Would he have flown into he crowd after loading up the plane with gas and whatever bomb making materials they found and killed more people?

If so, why use the guns?

He had an arsenal in the room. Weapons, bullets. In a hotel. Presumably the “NO SERVICE NEEDED” sign was out on his two doors? And he lucked up that no manager or staff members checked the room while he was gone?

He owned 3 planes.

I think that is an important point. It he really wanted to kill as many people as possible, mass casualties, he could have loaded his plane full of fuel and slammed it into a football stadium full of 70,000 people. If your sole intention to is kill a lot of people, that seems like the more destructive route.

So using guns and targeting this festival might have had a more personal reason to him. Or there was some other factor that went into his planning that we aren't aware of, yet.

Or maybe he kept some hope in the back of his mind that he was going to find a way to escape as he was planning all of this. Maybe he couldn't commit himself to full suicide until the end.
