As you probably guessed, these are not fireworks for the 4th of

July but, rather, the explosion of the Ariane 5, which happened 30 seconds

|

|

00:00:06,670 --> 00:00:09,250

or so after takeoff due to a software error. And this is
|
|
|
|

|
|
00:00:09,250 --> 00:00:12,020
|
|
just an example of what can go wrong when we don't build software
|
|
|
|
5
|
|
00:00:12,020 --> 00:00:15,600
|
|
and we don't test and verify and perform quality assurance of software

|
|

|
|
00:00:18,540 --> 00:00:21,250
|
|
and to build the Ariane 5 it took 10 years. The cost
|
|
|
|
8
|
|
00:00:21,250 --> 00:00:25,240
|
|
was around $7 billion and there were $500 million of cargo on board.

Luckily, at least there were no humans on the

00:00:27,280 --> 00:00:29,400
|

rocket. And you can find more details in case

00:00:29,400 --> 00:00:31,610

you're interested about the Ariane 5 accident in the
