Rocketry traditionally contains a lot of euphemisms like "off nominal situation". E.g. the self destruct system on rockets is generally called a "range safety package".

I do feel like it's distinct from corporate speak though. Rocketry euphemisms are really just science-folks hedging their bets. Sure the rocket is doing something abnormal but the cause and result of it won't be properly clear until some research has been done so "off-nominal" seems like an apt description in the meantime.
