Project CRS-7

Failed

Reason: HELIUM TANK OVERPRESSURE LEAD TO THE SECOND STAGE LOX TANK EXPLOSION!

Launch performance was nominal until an overpressure incident in the second-stage LOX tank, leading to vehicle breakup at T+150 seconds. The Dragon capsule survived the explosion but was lost upon splashdown because its software did not contain provisions for parachute deployment on launch vehicle failure.
