Not sure if anyone watches them, but SpaceX is going to attempt a test flight of SN15 possibly this afternoon.
On Youtube, we watch NasaSpaceflight -> https://youtu.be/rXG7W7skekw
About 4 minutes before launch, SpaceX goes live and we watch their feed.
SN15 stands for serial number 15.
SN8 - ran out of oxydizer on it's landing attempt, landed hard and exploded.
SN9 - had an engines fail to ignite on the flip maneuver and landed on it's side spreading flame and debris everywhere.
SN10 - Did the flip maneuver, had all 3 engines light, but had a methane leak. The landing legs did not fully deploy and it ended up leaning. It exploded shortly after landing. My wife and I were cheering and jumping that they stuck on on the pad.
SN11 launched in the fog. They don't need visuals to collect flight telemetry. On ascent, an engine had an issue burning up some avionics which caused problems on the flip maneuver so the internal guidance computer detonated the self destruct charges. Debris 5 miles away.
