It’s probably an effective way to light a car on fire.
At the base of the windshield is a water collection and drain system. This is usually all plastic and flammable. It also drains down to the ground.
So the primary point of ignition is the drain tray. The flames on the ground might catch some parts of the engine compartment on fire as well.
All fully armed and ready to launch.
Judging by how the rest of the crew scattered except the guy doing the launching, this isn’t the first time they have come under fire during a launch.
