The US military sometimes likes to add a spark to its air shows with a massive pyrotechnic display known as the “wall of fire.”
Most recently, the Marines did this at Marine Corps Air Station Cherry Point in North Carolina, as can be seen in this Sept. 26 video from the base. The “wall of fire” was around 1,000 feet long and estimated to be several hundred feet tall.
The “wall of fire” is usually the penultimate act. The finale is typically the headline performance by an aerial demonstration team like the Blue Angels or the Thunderbirds.
