Shape of a Raindrop

Factual Questions
1

I am wondering how izzit that a raindrop on its way down would have the “hamburger” shape as claimed by the website below.
Flat on the bottom but rounded on the top.

I had always thought it would be more like a teardrop instead:confused:

Wouldnt air shape it to be more aerodynamically sound then the said “hamburger” shape?

Anyone can clear this up for my brain?

Raindrops start out rounded, but as it falls the air pressure flattens the bottom, and the sides move out due to lesser air pressure.

A tear-shaped raindrop inside a no-smoking-style negation symbol is the icon of Bad Science. Check the link for their explanation thereon.
