Getting caught out with rain on our way back, I was tired and reacted slow with heavy hands and the wing was soaking and heavy. No injury and no damage, bloody british winter flying...Mistakes were made! haha :D
Was it a wake from the wing ahead? It does not look like conditions were too turbulent, it seems the wing ahead could cause the wake because of cross wind plus it appears you were on speed-bar ~60% it could contribute as well...
