Cornish Jack -
indeed!
Did S&R standby at a Gaydon display day, way back when and the DR's display started with a nine ship of three threes in vic, the leader lifting and immediately rolling inverted to climb away - heart stopping stuff!!
Was that Sept '69 ? If so there was a JP aerobatic group there at the same time & they went up together
Does anyone out there have pics of them flying together ?
