A spanner placed on a wing surface during a task is knocked off, falls into an open engine cowl and breaks a sensor connector. What does this event illustrate?
- a team error.
- Murphy's law.
- a memory lapse.
Explanation from PART66Online
This is Murphy's law: a failure path was left open, the task was repeated enough times, and on this occasion the path was taken. It is not a team error, which is a failure in the way two or more people coordinate their work: nobody miscommunicated anything. Nor is it a lapse, which is a failure of memory, as nobody forgot a step. The control lies in the task set-up: nothing rests on an aircraft surface.

I think it is skill based error

Hey Madhu!
Partially you right but skill based errors are errors associated with intrinsic variability of force, space or time coordination. Murphy's law is more correct answer. If spanner can fall and break something, it will. :)

this is an example of gravity at will!
But if you're in a Vomit Comet type A/C, on a parabolic arc, and you start to levitate,are you weightless,or are you just free falling?
Ans: Any object that orbits another object... be it earth, moon, Mars, is affected by its gravity,and is pulled toward it. You will be in a constant free-fall till your orbit decays and gravity overcomes your gravity and pulls on you.
