The piece of software was fine. It was done for Ariane 4 and worked as expected.

They re-used it for ariane 5 without checking/adapting it for work in the different environment (more acceleration & thrust). I don't even know what's the name for that kind of mistake. ^^

> See my other post, they effectively have sent something random ("diagnostics" instead of the data).

The software failed. It doesn't matter what it returned at this point. There is nothing to do but to fix the bug in the software.

If it returned "last number" instead of what it did, it would be considered a bug in the exact same way.

For R2, I suppose that they reused the tests from Ariane4 as well :D
