After the crash, an investigative team from the UK Department for Transport Air Accidents Investigation Branch attended the scene in co-operation with Strathclyde Police. The wreckage of the helicopter was removed to Farnborough for further forensic investigation. A report into the accident was published on 12 February 2009. In it, the AAIB did not reach a definite conclusion as to the cause of the accident, stating instead that "the helicopter crashed in a wooded valley while manoeuvering at high speed and low height. It was intact prior to impact, and the available evidence indicated that the engine was delivering power. The cause of the accident was not positively determined. Although no technical reason was found to explain the accident, a technical fault could not be ruled out entirely. However, it is more likely that the pilot attempted a turning manoeuvre at low height, during which the helicopter deviated from its intended flight path; whether due to the pilot encountering handling difficulties, misjudgement, spatial disorientation, distraction or a combination of such events. There were indications that the pilot had started a recovery but, with insufficient height in which to complete it, the helicopter struck trees in the valley and crashed, killing all four occupants."
Other rallies provide organizer-created "route notes" also referred to as "stage notes" and disallow reconnaissance and use of other pacenotes. These notes are usually created using a predetermined pacenote format, from which a co-driver can optionally add comments or transpose into other pacenote notations. Many North American rallies do not conduct reconnaissance but provide stage notes through the use of the Jemba Inertia Notes System, due to time and budget constraints.
A Fatal Accident Inquiry into the incident concluded, on 6 September 2011, that McRae was at fault for the avoidable helicopter crash that led to his death and the death of his passengers. Sheriff Nikola Stewart stated, after the 16-day inquiry, that McRae had been engaged in "unnecessary and unsafe" low-level flying at the time of the crash.
Unlike the requirements for the preceding Group A cars, manufacturers were no longer required to build "homologation specials" in order to meet approval. The base model did not need to have all the characteristics of the WRC car, as evidenced from cars such the Peugeot 206, 307, Citroën Xsara and Škoda Fabia, which during this period had no road car variant with a turbocharged petrol engine or four wheel drive. One of the requirements was a minimum length of 4000 mm; the standard Peugeot 206 had an overall length of 3835 mm and Peugeot had to produce at least 2500 units featuring extended bumpers to comply with the required dimensions.
The First World War brought a lull to rallying. The Monte Carlo Rally was not resuscitated until 1924, but since then, apart from World War II and its aftermath, it has been an annual event and remains a regular round of the World Rally Championship. In the 1930s, helped by the tough winters, it became the premier European rally, attracting 300 or more participants.
In many rallies, including those of the World Rally Championship (WRC), drivers are allowed to run on the stages of the course before competition and create their own pacenotes. This process is called reconnaissance or recce. During reconnaissance, the co-driver writes down shorthand notes (the pacenotes) on how to best drive the stage. Usually the drivers call out the turns and road conditions for the co-drivers to write down. These pacenotes are read aloud through an internal intercom system during the actual race, allowing the driver to anticipate the upcoming terrain and thus take the course as fast as possible.
Built by the freshly created Advanced Vehicle Operations at the Ford Aveley plant in Essex, the Mexico went on sale between 1970 and 1974 with a 1600cc pushrod ohv engine. It cashed in on Ford’s success in the London-Mexico Rally of 1970. With a shade over 90hp, the Mexico could reach a heady 99mph, but this was enough to light up the rubber around the 13” steel wheels mid corner, giving you easily controllable drifts at relatively safe speeds and almost perfect balance.
Initially, most of the major postwar rallies were fairly gentlemanly, but the organisers of the French Alpine and the Liège (which moved its turning point from Rome into Yugoslavia in 1956) straight away set difficult time schedules: the Automobile Club de Marseille et Provence laid on a long tough route over a succession of rugged passes, stated that cars would have to be driven flat out from start to finish, and gave a coveted Coupe des Alpes ("Alpine Cup") to anyone achieving an unpenalised run; while Belgium's Royal Motor Union made clear no car was expected to finish the Liège unpenalised – when one did (1951 winner Johnny Claes in a Jaguar XK120) they tightened the timing to make sure it never happened again. These two events became the ones for "the men" to do. The Monte, because of its glamour, got the media coverage and the biggest entries (and in snowy years was also a genuine challenge); while the Acropolis took advantage of Greece's appalling roads to become a truly tough event. In 1956 came Corsica's Tour de Corse, 24 hours of virtually non-stop flat out driving on some of the narrowest and twistiest mountain roads on the planet – the first major rally to be won by a woman, Belgium's Gilberte Thirion, in a Renault Dauphine.[unreliable source?]
Rising investor confidence also indicates a rally, and it is perhaps more powerful than any economic indicator because when investors believe something is going to happen (a rally, for example), they tend to take action (purchasing shares in order to profit from expected price increases) that actually turn expectations into reality. Although it is an objective concept, investor sentiment shows through in mathematical measurements such as the put/call ratio, the advance/decline line, IPO activity, and the amount of outstanding margin debt.
