Ruby Tuesday brings me back to an air show in CT in 1985. This is a pair of aerobatic stunt planes making that sharp, nearly vertical climb to the safe altitudes before they perform their nearly vertical dive toward the ground, pulling up at just before the seemingly (to the viewer) last gasp of altitude before the danger of the ground coming up to hit them. But not to worry, their power (250-300 HP), the light weight (~1400 lbs / 640 Kg) and large lift producing wings keep them off the ground. The artistry and skill of the pilots giving us on the ground a look of amazement as they continue their routines to a safe landing. The red stripes don't hurt, either...See the number of wonderful rubies at Mary's always fun meme!
