Did NASA invented thunderstorms to cover up the sound of space battles

Nope.

Explanation:

No, I do not believe that NASA invented thunderstorms to cover up the sound of space battles. For example, Benjamin Franklin is noted to have experimented with lightning in the 1700s, well before NASA or NACA existed. Therefore, NASA did not invent the concept of thunderstorms.

if you expect the unexpected is it still unexpected??
