John: Excellent.  Is it a failure or attack?

Me: It depend on whether Kelvin try to recover the start up register of your microsoft window or not. 

John: Kelvin never try to recover the start up register of my microsoft window.

John: Yes,. 

Me: Consequently, the impact is forever and unrecoverable.

Kelvin: Yes,.

Daniel: Every time, you hack the microsoft window of John, John must re-install the window and all the informations of his computer lose. Then, does not the airport need to re-install their system? Why does not all the informations of the airport system lose?

Kelvin: The airport encounter a short-term failure. I let their system be disabled for 10 hours. And then, I let their system recover.

Daniel: Every time you hack John, you never let the computer of John recover. Now, you hack the system of the airport. You let their system recover ? It's unfair to John. John must re-install his window for 30 times. All the information inside John's computer is lost for 30 times.

Kelvin: John encounter a hacker's attack. The impact is forever and unrecoverable. The airport encounter a short-term failure. The impact is short term and recoverable.
