They were the only supplier who told us our schedule was wrong before we signed. Everyone else agreed with us and then missed it.

We had lost confidence in a channel that had never failed a single test. Vanguard found an eleven-year drift in a cable penetration nobody had looked at since commissioning. The chain now reads what the physics says it should.

The FPGA at the centre of our bus went end-of-life with two spacecraft still to build. They had a costed set of options in front of us inside a week, and they recommended the one that was hardest for them.

Our first DAL-A programme was fourteen months in and going sideways. They did not tell us it was fine. They told us exactly which nine months of work we were going to have to redo, and then helped us do it.

Nuisance disconnects across the retrofit fleet went from a weekly conversation to something we stopped tracking. The pilots noticed before the data did.

Losing 900 milliseconds of data before an engine anomaly is the kind of thing you only accept once. Their controller records everything, all the time, and the first time we needed it that decision paid for the whole programme.

They ran in shadow mode alongside our existing system for seven months without once pushing us to cut over. The safety case was built on measurement rather than argument, which made the regulator conversation short.

The documentation is written for the engineer who will inherit this in year eighteen, not for the one signing it off now. After two decommissioning projects with incomplete records, I cannot overstate what that is worth.
