SpaceX launch live blog: Latest updates as Falcon 9 rocket set to explode
Elon Musk says dramatic abort test will see Falcon 9 rocket 'destroyed in Dragon fire'
SpaceX has launched and exploded a 500-tonne rocket in mid-air as part of the last major safety test before sending astronauts to the International Space Station (ISS).
The In-Flight Abort Test saw the Falcon 9 rocket experience a planned "rapid, unscheduled disassembly" shortly after take-off.
The launch was originally planned for Saturday but was postponed until Sunday due to adverse weather conditions.
Sunday's launch was delayed three separate times but a six-hour launch window allowed it to eventually lift-off at 10.30am ET (3.30pm GMT).
