A couple of years ago I read an old article by (I think) Neil Williams on formation flying. If I remember correctly he describes in it how the Vulcan diverted to St Mawgan which was also hosting a BOAC 707 doing crew training circuits. The 707 offered to formate with the Vulcan to give a visual assessment of any damage - then proceeded to terrify the Vulcan crew with their inept attempts to join up, probably scarier than anything else that happened to them that day.
