Problemilla

De hecho, la conversación fue asi:

Swigert: "Hey, Houston, we've got a problem here."

Capcom Houston: "This is Houston - say again, please."

Lovell: "Houston - we've had a problem. We've had a Main B Bus undervolt,"

Capcom Houston: "Roger. Main B undervolt. Okay, stand by, Thirteen, we're looking at it."

Precisamente.... con pelos y señales
