I remember an airshow in UK. Early 60s. Excellent static displays, spectacular flypasts, and so on.
They left the most memorable excitement for the finale.
It was announced on the Tannoy that the airfield was being invaded by (Dr Who) Daleks. (Actually some chaps whizzing around the runways on go-carts done up as Daleks.) They were busy exterminating the defenders with their ray-guns.
The announcer said a squadron of fighters had been scrambled, and were on their way to deal with the invaders. These turned out to be a collection WW2 prop planes, which strafed the Daleks. Guns actually firing (presumably blanks). They knocked over a couple of Daleks, and then biffed off.
Next we heard that a squadron of ground-attack E-E Lightnings were on their way. They too knocked over a few Daleks, to great cheers from the crowd. The Lightning was the first aircraft in the world that could fly vertically upwards, and the whole squadron left the airfield by standing on their tails, in unison, in formation, and climbing straight up into the sky.
Now the stage was set for the piece de resistance. A squadron of Avro Vulcans. The heavy brigade. The announcer rallied the crowd with patriotic cries of Go get 'em, chaps, and we could hear the Dam Busters March playing over the loudspeakers.
We could see them coming in from a long way off. The Vulcans were Big planes - you couldn't believe how they grew in size as they approached. There was hardly any sound until they were almost over the runway. And then there was Noise. The Vulcans opened their bomb doors and dropped (flour) bombs on the Daleks, wiping them all out.
Once again, the RAF had saved Britain from the attackers. The crowd (all 200,000 of us) went home excited and happy, following the entertainment experience of a lifetime. (You can see I've remembered it.)
They don't do them like that anymore.
