During my JP course I was sent on my first solo nav, five minutes after a pal of mine went. He orbitted over Wetherby, one of the turning points, due to him being uncertain of position. I therefore inadvertently caught him up without him being aware. Once I'd done so, I just dropped back a little and followed him round the route.
He wasn't too chuffed when I asked if he wanted a debrief
Shortly afterwards my QFI came up to me (he'd been DI in the tower and watched us on radar) and asked if I'd enjoyed my formation!
