There are 2 aircraft over Warwick. The Aero Sotravia Beech B20l at 27k feet who do the broadcasting and an NPAS Vulcanair at 1.5k feet. My understanding is from reading about these NPAS aircraft is that they have nothing to do with the broadcasting and are operating in a capacity to what an NPAS helicopter would do but are able to stay over one area for longer hence I suspect why they are being used at events that last for several hours ie the road race today.
