I GENERATED THE DATA IN POUND-FORCE SECONDS. THE SPECIFICATION SAID NEWTON-SECONDS. THEY FOUND IT AFTER THE ORBITER BURNED UP.

The Redstone Climate Orbiter burned up during insertion into the Martian atmosphere due to a navigation data mismatch. For ten months, data was submitted in pound-force seconds instead of the required newton-seconds, going unchecked by multiple teams until it was too late.
