The famous yachtsman Francis (later Sir Francis) Chichester
actually began his career as a pioneering aviator. In 1931 he
made the historic first solo flight from Australia to New Zealand
across the Tasman Sea and during this flight he was suddenly
startled by a group of flashing lights moving at high speed
across the sky.
One of the strange objects approached his aircraft - he described
it as "like a silver pearl and flashing like a searchlight". The
moved in front of his aircraft before disappearing.
For well over 7 decades Pilots, both military and commercial,
have reported the sighting of objects that they could not identify
For a detailed account of some highly relevant sighting reports see:
Of course, during the Second World War allied pilots, returning from
missions, began to report the sightings of strange "balls of light"
which hovered close to their aircraft. The concern of Allied military
chiefs began to grow when these reports not only increased in numbers
but even stranger, included reports of disrupted electrical equipment
in aircraft in the direct vicinity of these unidentifiable
objects.These mysterious objects became known as "Foo Fighters".
