The airport adds, “We use many different aircraft-designed mock-ups, and purposely ignite the mock-ups to train these fire fighters. During training periods you will see black smoke as a result of these training fires. The rising smoke that you see quickly dissipates into the atmosphere which is a way to know the smoke you see is from the training fires. The DFW FTRC uses clean burning propane and a liquid fuel called E-III – both are environmentally friendly.”
