Really pleased to see the improved reliability of the Raptor engines and TVC system compared to IFT-1. The sight of 33 healthy Raptors firing simultaneously was stunning!

Was it the launchpad explosion on ift 1 that broke the hydraulics? Or was that an issue with the system itself?
The system itself. It seems like the hydraulics failed because the computers on IFT-2 got destroyed in fires/engine failures
During ascent, the vehicle sustained fires from leaking propellant in the aft end of the Super Heavy booster, which eventually severed connection with the vehicleβs primary flight computer. This led to a loss of communications to the majority of booster engines and, ultimately, control of the vehicle.
