Here’s an extract from the section on notorious bugs.
"Ariane 5, June 1996. The maiden launch of the Ariane 5 rocket blew up 40 seconds from liftoff. The rocket and its four satellites were uninsured and worth $500 million. The proximate cause of the crash was an overflow error due to an attempt to convert a 64 bit floating point value into a 16 bit integer. This error occurred in code that was non-functional after liftoff, when the error occurred. The Inquiry Board report provides details regarding the software failure and the design policies that lead to it. A note in the Risks Digest indicates that a complete system test would have found the problem but was vetoed for budgetary reasons."
