Admit you're a good example of a little knowledge being a dangerous thing and there are many people out there (and on here by the looks of it) who seem to know a little bit more about a lot more things than you do.
Waiting for you're FINAL post on the matter like you seem to do in all your threads.

No need to be rude Grimbo although from your posts it must be difficult not to be.
If I have a little knowledge, then it is a hell of a lot more than the people you so kindly refer to.
OK Grimbo, I admit that I made a mistake and apologise for it. A stupid over-sight on my part. Start again.
Even at a few feet, shape comes into it since air resistance does matter when a body is light and has a relatively large area.
A single feather with the same mass as a piece of lead, both having the same shape when dropped from a few feet, will hit the ground last due to the feathers many segregated strands creating drag. But a bag of feathers weighing one pound and a bag of peas weighing one pound will hit the ground at the same time.
In a vacuum, the identical feather and lead particles will hit the ground at the same time.
Now Grimbo, I resent your insulting personal remarks,which are quite unnecessary, so you are going on my Ignore list.
