This can be corrected with controls that influence the three ways a craft can move in the air: pitch, yaw and roll. Pitch refers to an up or down movement of the nose or tail; yaw is a side to side to side movement of the nose and roll (or bank) is said to occur when the plane rotates around its longitudinal axis – the line that passes through the plane from nose to tail. There are two other types of stability: positive stability when the aircraft will maintain its attitude without constant control input and will eventually return to its intended position if its path is disturbed, and neutral stability when the craft will not return to its trimmed setting without control input, but will swing from side to side without moving further and further off course. All of which suggests, reasonably enough, that you don’t want relaxed stability in any aircraft – it should be designed out at the offset. There are, however, situations in which a form of instability is considered highly desirable. Certain military craft are deliberately designed with inherent instability and equipped with flight control computers to compensate. Such craft will instantly lose stability if computer control is suspended. What would appear to be a form of designer recklessness actually brings the great advantages of being able to change direction with minimal intervention of the flight surfaces (the flaps, elevators, rudder etc). Responsiveness is increased and the craft can manoeuvre in dramatic and unpredictable ways. It will confound and frustrate its enemies by tossing itself around in the air.
It is hard to resist the thought that these ideas, and the terms in which they are expressed, could be fruitfully applied to certain contemporary social situations. The nature of stability, for example, is not just a matter of personal psychology but an effect of the ideologies that compete to secure a dominant definition of the concept. One man’s stability is another’s death-in-life. In the 60s, for example, stability was what your parents craved and you despised. Their ‘small “c” conservatism’ – a symptom of what was, in part, a widely dispersed postwar posttraumatic stress disorder – made them, in your view at least, unable to change direction without considerable forewarning and persuasion. Your view, consonant with the aeronautical theories with which you were not familiar, was that their stability would lead to their undoing. It had no flexibility insofar as it would guide its adherents further and further into inaction then rigidity. The aeronautical version is much the same: stability is synonymous with the maintaining of a set position but implicit in this condition is its own decay.
The new instability was characterised by individuals easily knocked off course and prone to erratic behaviour. They were also highly responsive, able to react efficiently to rapid state changes and capable of high-volume decision making in short time periods. Affinities between stock market traders, military personnel and ‘accomplished shoppers’ became apparent, as did a willingness to obey orders.
The latter quality has proved useful when the latent pathology of this malleability is presented as a psychiatric issue. Fortunately the reshaping of psychotherapy under capitalism has produced a treatment based on the issuing of orders rather than a consideration of such tiresome matters as the unconscious. What you do, right, is simply tell the patient to think differently. It’s the patient’s ideas that are the problem. Change them and the patient is relieved of their problem. You have to go at least six times, mind you. These things can’t be done overnight. Cognitive behavioural therapy – why worry when you could be at work not worrying? It’s probably more sophisticated than that, but not a lot more.
So we are all soldiers now. A militarised technology contributes to a militarised psychology in which the unforeseeable is preferred to the reliable. The unforeseeable, apparently patternless, can be patterned. You want fighting men and women who will instantly obey orders, highly defined individuals who are careless, unattached, impetuous and obligated. With their yaws muzzled and their pitches perfected their disorder is a small price to pay for order.
