Well, for one it was in the Indy, and that's important because they do care about the environment, when the red-tops have columns by Jeremy Clarkson rather than columns and blogs about him.
And so far the Indy, nor any like them (that I've seen) has not managed even a quiver of an eyebrow at this whole jet thing.
If the whole effort was time-critical, I could see some justification, but the guy is sitting on the subs bench. Why can't he take the train? Or at least a plane shunting around a few hundred at a go? Especially as there seems to be a 12 person entourage involved.
