As you already said, snowflakes are complex things, but one constant is that they all generally fall at a gentle rate compared to hail and rain because they are less dense than these items. So, while large, the density of the snowflake should be comparable to a small one, so should fall at the same rate.

After all, a feather weighing a tonne would still fall like a feather because it is other factors, like surface area and aerodynamics, drag etc that determine the fall rate, the same applies here. The reason it would've been able to be observed, and likely isn't a wind up is for that reason, it would likely have fell to the ground safely, like most snowflakes.
Do you really believe all that you have said ? Preposterous.

You are wrong in practically every word. You must have left school whilst in short pants to say things like that. How utterly ridiculous.

If a feather weighed a ton, it would drop like a ton. It would no longer be a feather. Mass, shape and surface area determine drag. Terminal velocity is proportional to mass. The reason a feather floats down slowly is that it has a tiny mass and a large surface area. If it weighed a ton, it would drop like a ton and make a huge crater in Mother Earth`s crust on impact.

Come off it, pick up your text books and start again.

Have you never heard the oldie - "What falls faster, a pound of feathers or a pound of peas ?"
