There is nothing to ‘buy’... Condensation trails occur at about 26,000 feet... That’s how they are created... Below that altitude, they aren’t created. It’s not a button in the cockpit... It’s the atmospheric conditions that create them.
Answer:
Contrails, or condensation trails, are clouds formed when water vapor from aircraft exhaust condenses and freezes at high altitudes. While they can disappear relatively quickly under certain conditions, they don’t typically stop instantly in mid-air. Several factors, including atmospheric humidity, temperature, and aircraft altitude, influence the formation and persistence of contrails.
