We all make mistakes.........Anyone who says he doesn't make mistakes is a liar. You make them, learn from them and move on.
By the sounds of it this TAP Chief pilot was chosen to do the 'airshow' because he was very good. Then comes display day ..........oops ! He makes a mistake.
Unfortunately there is a difference between the KLM incident and this incident. The simple difference is the KLM Chief pilot did not practise in the sim how close he could leave it before applying full power and just clearing the other 747 on the runway !!
When most of us make mistakes we have a safety net underneath us, sometimes on very rare occasions that net doesn't catch us
but what we don't do is considerably reduce the size of the net.
Perhaps next time he should use one of those Portuguese fishing nets.
