Firefly Tantrum Launch from Vandenberg SFB

Filmed from a fallback/forward observer location approximately 2.5 miles from the launch pad.

The tone at the start of the video is an alert broadcast over the safety net indicating the vehicle is still on the pad. The female heard over the loudspeaker is one of my coworkers, while the two male voices you may hear are another two of my coworkers who are performing forward observer functions. The cheers are from some of the Firefly team.

"Ignition", "X good engines", "Liftoff", and "Program program" are calls made by the forward observer (Back Az or Program), telemetry observer, forward observer (Back Az or Program), and forward observer (Program). Other calls can be heard being made and acknowledged throughout the launch.
