The leader Virginie Guyot was n°4 last season, and deputy leader of the Patrouille de France.
That's the way they usually do it in the Patrouille. The #4 is also known as 'charognard' (=vulture), because she/he sits on the shoulder of the leader and takes over when she/he departs.
Virginie was a recce pilot on Mirage F1CR (2/33 'Savoie' Sqn at Reims) before joining the Patrouille
