Commando Comic #4215 'Second Best?' (2009)
 
Bill and Johnny King were twins, but Bill was always that much better at any sport you cared to mention. So Johnny learned to live in his brother's shadow. The same thing happened when war threatened. Both were dead keen to fly, but it was Bill who qualified as a pilot while Johnny was ruled out on medical grounds.
 
Yes, Bill was certainly destined for glory, but it was what Johnny could do one dangerous day which would decide which of the twins would survive... if either!
