Near the end of Wonder Woman, Steve flies the plane into the air to save everybody from the poison gas. However, Chief puts bombs in the warehouse where the gas was stored and the warehouse blows up. Was that not harmful to people in a 50 mile range like it would be if it was in the plane? How is it different?
I believe that the whole output of the poison manufacture was on the plane, while the warehouse only contained the raw materials and the machinery to build more. So the factory could be safely blown up without danger, while the plane full of poison needed to be destroyed at a great distance.
