Is the word “bomb” muted in in-flight movies?

I was recently on a transatlantic flight and watched the movie Steve Jobs on the plane’s entertainment system. Every movie I tried, including that one, had a message right at the start saying the movie had been edited for content.

In one scene, the caracter of Steve Wozniak is fiddling with a watch and the character of Steve Jobs makes a joke it looks like he’s messing with a bomb. Those words were muted. The word “bomb” (and one or two words around it) were gone from the movie. I even rewinded to make sure, and the words were indeed gone.

Is there some weird law that forbids the use of the word in in-flight entertainment systems? It there is, it’d be particularly weird since you need to plug headphones to listen to the movie in the first place, so it’s unlikely you’d cause hysteria. In addition, the word was pronounced again later on in the movie but wasn’t muted then. It was less clear audibly, though, so it’s feasible it wouldn’t have been caught by the automated system (if any is used).

The airline was TAP, and the entertainment systems were individual per seat.
