Ummmm. FWIW,
I have flown a Druine Turbulent under a hand held banner about 7 feet off the ground in line astern with 6 other Turbs. Not very fast (about 70kts I think), quite exciting really (absolutely) certainly good fun. Then we would cut toilet rolls also in line astern, burst balloons and flour bomb 'anything.' Then we had a tied together formation (Tiger Club stuff) of four Turbs from takeoff, display, formation flying, to touch down still tied together! Never broke a link!
Try that in Hunters, Jags Hawks or Lightnings!
