Serendipity

Extract

An historical survey gives an opportunity to reflect on a few selected episodes which seem to have had a significant influence on shaping later events. I need not remind you that reflections on aircraft mostly having two-dimensional curvature with surface finish falling short of mirror standards, and not only is the image probably distorted but also the perspective depends very much on where the observer stands. Moreover, also, quite important objects can be thrown right out of vision.
