Argus pulsejet run at the Military Aviation Museum in Virginia Beach, Virginia on February 6, 2021. This is the propulsion for the German V-1 flying bomb from WWII. The engine tube is original. Compressed air is used to provide airflow at the start. Later in the video is the museum's V-1 that was found in it's underground storage in Germany.

Unfortunately, the video can't capture the vibration you feel in your chest when this beast runs.
