In late June 2015, CRS-7 launched a Cargo Dragon atop a Falcon 9 to resupply the International Space Station. All telemetry readings were nominal until 2 minutes and 19 seconds into the flight when a loss of helium pressure was detected and a cloud of vapor appeared outside the second stage. A few seconds after this, the second stage exploded. The first stage continued to fly for a few seconds before disintegrating due to aerodynamic forces. The capsule was thrown off and survived the explosion, transmitting data until it was destroyed on impact.  Later it was revealed that the capsule could have landed intact if it had software to deploy its parachutes in case of a launch mishap.  The problem was discovered to be a failed 2-foot-long steel strut purchased from a supplier to hold a helium pressure vessel that broke free due to the force of acceleration.  This caused a breach and allowed high-pressure helium to escape into the low-pressure propellant tank, causing the failure. The Dragon software issue was also fixed in addition to an analysis of the entire program in order to ensure proper abort mechanisms are in place for future rockets and their payload.
