Track layout on current runway - note VTOL tethering pads next to "Hammerhead"
Top Gear Track in location on 1938 Map
The BBC Top Gear track has been laid out on the main runway of the former WWII RAF and RCAF air base. The perimeter roads used for Gambon and the finish line were laid over the route of original B-Roads that were ripped up when the airfield was constructed in 1941. One cottage, Broadmead, was situated where the TopGear FollowThrough is now, but the cottage was lifted whole and winched half a mile on rollers to the otherside of the airfield.
The main runway has the rarity of the Vertical Take Off and Landing pads, (VTOL) used for the tethering of jump jets such as the Harrier, Kestrel and the P.1127 . These are also located on aprons that but up against the main runway and are within the Operational Readiness Platform [ ORP]. Beneath these gratings is a large void chamber to take the hot air, condensation and gases from the downdraft of the jet engines of the aircraft. Also within the eastern Engine Testing Pen there is a similar arrangement that is a unique feature to Dunsfold.Continue reading “VTOL sites”
The Bomb Stores Site has two access roads with seven concrete hard standings in between and earth banks separating each hard standings or bays. These bays were used to store the bombs which were placed on wooden frames. The earth banks that separated each bay gave a degree of isolation should there be an accident and these are still visible.Continue reading “Bomb Stores Site”
It is a rare feature that all three runways survive at their original lengths and are connected with a complete perimeter track with at least 75% of the aircraft hardstanding.
Two runways are much rarer than others elsewhere in the UK as they have a large number of the Mk II airfield lighting fittings intact, together with the cast-iron drains and French drains along each side of the runways.
The runways were constructed for a Class ‘A’ bomber airfield. The white concrete of the runways and perimeter track were sprayed with a mixture of tar and wood chippings. This dark textured finish was optically non-reflective and from the air closely resembled grass. The chippings also added extra surface grip without damaging the aircraft tyres.
