The Columbia Accident Investigation Board called this tendency the "normalization of deviance" – a gradual acceptance of events outside the design tolerances of the craft simply because they had not been catastrophic to date.
Vyšetrovacia komisia nehody raketoplánu Columbia nazvala túto tendenciu ako normalizácia odchýlky – postupné prijímanie udalostí mimo toleranciu návrhu raketoplánu jednoducho preto, že dovtedy nespôsobili žiadnu katastrofu.
