The Red Arrows are the Royal Air Force Aerobatic Team, formed in 1964 and now flying the BAE Systems Hawk T1 on displays worldwide. Their signature red, white and blue trails are made by injecting diesel and dye into the jet exhaust from a centreline smoke pod. Calls such as smoke on and smoke off are heard in cockpit and airshow recordings shared by aviation fans online, and the phrase has become shorthand for the start of a formation display sequence.

RAF Red Arrows Smoke On radio call from a display flight, heard as the team releases coloured smoke trails during aerobatic airshow routines.
This is the short radio call that signals the Red Arrows smoke systems switching on during a display. A pilot's clipped voice cuts through jet noise and cockpit radio static, giving the moment a tense, precise feel before the coloured trails appear. At just over two seconds it lands like a cue rather than a full clip, capturing the instant anticipation builds in an airshow crowd. Editors use it for its instant recognition among aviation fans and for the clean, authoritative snap it adds to a reveal.
