The Sloppy Code That Blew Up a $370M Rocket

The Ariane 5 rocket explosion was caused by a software bug where a 64-bit floating-point number was converted to a 16-bit signed integer, exceeding its range and triggering an exception that shut down both inertial reference systems. This led the flight computer to steer based on garbage data, causing the rocket to break apart. The speaker argues that such numeric overflow and type conversion errors are common in programming, and that using unsigned integers or fixed-width types without careful consideration can lead to catastrophic failures, as also seen in the Heartbleed vulnerability.
