The wise son. Imagine a different schoolboy in the cabin of that 747. He is asking his father to explain to him, as much as possible, the laws, the statutes and the commandments of the Torah. His question reveals that there's no one behind the control column. It's just the autopilot speaking.
Much attention is given in the Torah to the ten plagues and to Egypt's downfall.
We are not rejoicing at our enemies' ruin. Each plague demonstrated how the mighty empire was like putty in G-d's hands. This was not the last time Egypt would suffer devastation. The Prophet Yirmiyahu foretells Egypt's fall to Babylon. Egypt gives way to Babylonia, and Babylonia later falls to Medio-Persia.
