Grounding the Fleet

I wonder whether it’s NASA or the media who like the phrase ‘grounding the fleet’. It’s like when the pope was dying, and everybody was falling over themselves to say ‘last rites’. It sounds all dramatic and isn’t something that comes up very often, so I can understand the enthusiasm. Still, it’s not like NASA have more than one shuttle launched at a time, and they’re not actually bringing the existing shuttle back early. So ‘grounding the fleet’ isn’t really very accurate. But I’m just a pedant, and shall shut up now.
