Apollo 15 Launch (Multi-Screen)

Video from the channel lunarmodule5 about Apollo 15, linked on its Above Ten Thousand entry. Duration: 6:17. Language: English. Video type: Launch.

The video shows the launch of Apollo 15 in 1971 aboard the AS-510 vehicle and presents it from several cameras at once in split screen. In the background are the launch room commentary and communications with the crew. Commander Dave Scott and lunar module pilot Jim Irwin are named.

The video begins two minutes before liftoff. The launch room team monitors more than 300 critical parameters, the second and third stage tanks are pressurized, and the vehicle switches to its own batteries. Scott performs the final check, the guidance system alignment, and guidance switches to internal at 17 seconds. The ignition sequence starts at 9 seconds and liftoff occurs at 9:34 a.m. Eastern Time. After clearing the tower come the roll program and the passage through maximum dynamic pressure. The commentator explains that each of the first stage's five S-IC engines burns about 3 tons of fuel per second.

First the center engine shuts down while the other four keep running. Then comes first stage separation, and the second stage ignites with its five engines in good condition. Afterward the escape tower is jettisoned. The video ends as the vehicle approaches 10,000 feet per second and everything proceeds as planned.
