After passing the static water test, we move on to the dynamic water test. Instead of pulling pressure from the chamber, we use an airplane engine to propel the water spray at the skylight. It makes a lot of noise and shakes the skylight. This test also runs for 15 minutes. Witnesses are inside the chamber during this test. For first-timers, it can be memorable having that propeller cranking away so close to you.
