We have all heard about the Challenger disaster.
Reading the Vehicle breakup subsection, this sentence made me very curious:
The external tank at this point suffered a complete structural failure, the LH2 and LOX tanks rupturing, mixing, and igniting, creating a fireball that enveloped the whole stack.
I know it is not the explosion which destroyed the whole vehicle but aerodynamic forces, but I wonder:
- How much liquid fuel and oxidizer were left in the external tank at the time of its destruction?
- How many seconds were left before SRB separation?
I couldn't find any information, so thank you for your answers!
