In 1999, NASA's Mars Climate Orbiter crashed due to a navigation error caused by a mix-up between the spacecraft's navigation software using metric units (newton-seconds) for measuring thrust, while ground-based software provided data in imperial units (pound-seconds).

From the looks of it, the #NATS meltdown and the development style of Austrian software company #Frequentis will provide an excellent example for programming teachers for years. It might even surpass #ariane5 floating point, NASA's #MarsClimateOrbiter's meter vs feet parachute and #Therac25

Ajoutons pour l'anecdote que la #Nasa a perdu une sonde martienne🛰️, #MarsClimateOrbiter, car un de ses prestataires avait utilisé les unités impériales au lieu des unités du système métrique internationale. C'est ballot.
