The first Falcon 9 flight was launched from Cape Canaveral on June 4, 2010, with a successful orbital insertion.
The second launch of the Falcon 9, and the first of the SpaceX Dragon spacecraft atop it, occurred December 8, 2010, The Dragon spacecraft completed two orbits, then splashed down in the Pacific Ocean.
All of their launches had delays....for the same thing...engine sequence.
2 launches is a vision for you?
I was there for the first launch at Canaveral...supporting it for the Eastern Range.
I need no education on when and where.
I’m giving you insight on what and why.
