More importantly, does the flying fly contribute to the airplane staying aloft?


Actually, yes.

It kept Charlie awake.

Hi Satt: "ALWAYS implicitly assumed" Now I understand why so many non-engineers think alternative energy is cost effective. Neil

I just started a thread on this and then was told there already was one.

I had heard this before and from what I remember, I was told that yes, the fly would add weight because even air inside the plane adds weight. Does that make sense?

if the windows are open wouldn't the fly be sucked out of the plane and therefore his weight wouldn't be there?

How do you know it was a he?

Mebbe she was a she, and full of eggs?

Damned dumb bear!

Read the thread, Momma!

Supposing windows open (!) and that the air flows smoothly through the plane, you cannot conclude that the fly adds its weight to the plane itself.


That must be one fast fly to keep up with a moving plane in midst of full airflow.

Momma, your previous question on the other thread involved a "closed" plane, which has a relatively simple answer.

They are complicating this situation by proposing an open plane and a fly which is "in between" in some way.

The object of their question is to disturb the answer to the simple problem (of a closed plane) by making it less clear where the downdraft of the fly is primarily felt.

However, without going into the physics of forces, it seems to me that any fly which is keeping up with a plane is by necessity caught in an airmass which is moving with the plane, and therefor the fly still adds weight to the plane. If the fly becomes involved with an airmass which is not moving with the plane, then likewise it's weight will no longer be involved with the plane (and it will quickly lose sight of the plane).

Thank you Rosborne,

I did notice that "my" plane was closed and the other wasn't. I have been reading all of these posts with lots of interest. I'm not that great at science but I do find this all very interesting.

Illustration Question

A man rode up to the local feed store, bought a sack of feed, slung it on his shoulder, got back on his horse and rode off.

He allowed that it was easier on the horse that way Smile
