Nice picture. Done a couple of air shows with the wing hoses trailed at low level, once with a couple of Lightnings close behind them, but don't ever recall trailing all three at low level
By the way, small point but the term is "hoses trailed" not "drogues winched out". The hoses were pulled out by the airflow acting on the drogues against the steadying control of hydraulic motors (electric motor for the centreline) which stopped them hurtling out and disappearing earthwards!
