The photograph (right) was taken near Maldon, Essex, in the UK, looking directly overhead. It appears to show the result of an aircraft flying through thin cloud and dispersing it along its flight path. If an aircraft was responsible it had long since passed when the picture was taken. Is this a common sight and what mix of conditions is required to produce the effect?

if you could design a plane to safely land upside down would the earths gravity feel as if its pulling you upwards for a moment. If not what would you experience as you adjust?

Surley you wouldn't just suddenly flip fight over as there is nothing to determim which way you would tern but it has to happen some how but how?
