Fruity puzzle resolved

Before you think I have morphed into a total numpty and to put Thomas’ mind at rest, who kindly mailed me regarding this matter: The orange that Petzl refers to has nothing to do with fruit (or beg) but rather refers to the colour orange in Henry Margusity‘s thunderstorm classification system, which defines a scale consisting of five categories: TS1, TS2, TS3, TS4 and TS5, with TS5 being the most severe in terms of damage and impact.

I still think the idea of climbing in fruit is funny.

But hey, you know what they say: truth is stranger than fiction.
