Thickness would be a factor as to it's rigidity - how well it holds it's 'flatness' vs. how much it bends and flops. I think a placard would reach it's terminal very quickly, like almost instantaneously, so I don't think you'd need a lot of altitude.

I will find out exactly how thick it is..Eric might have that as well. it's not very thick at all. even if I use decal paper the damaged one would probably stick together since it's torn towards the center..

With the protective backing on the placard it's almost the same thickness of poster board.the backing is thick and heavy..actually, it is the same thickness running my finger over the two..

I'm not sure how to measure the thickness. Perhaps the thing to do is test out your drone drop system and I'll buy another real placard that we can use for a drop if your system works.

The problem will be the adhesive behind it..even placing it into a holder. the damaged one will surely flip and stick together unless you have an idea to remove the adhesive or at least 90% of it? a micrometer will tell the thickness which I can find out tomorrow..

I'm absolutely certain I can neutralize the adhesive on the back.

I'm aware of a product that works wonders for removing the adhesive. My ex-girlfriend uses it regularly with her work and it should work perfectly.

I'll buy a few more placards this week and give it a shot.

Ok, the drop system will be like taking a dvd case. lay down and you would open one side, not the front or back. this will make a pocket. one side gets secured to the landing gear with string while the other side has the string to the release. once you hit the remote it drops causing the contents to come out. it should work..

ITS ALREADY BEEN DONE!

Sandia Labs Report. by Bustamonte 1968
Free-Fall Rotation and Aerodynamic Motion of Rectangular ...

PDF
It is believed that a rectangular plate will continuously autorotate about an axis which is free in flight. This behavior may be compared to the motion of a strip of paper of aspect ratio two or more. .... When dropped in still air, the strip rotates and descends along an inclined path. When dropped in other conditions ...

This is the report that Hominid and others used when evaluating the placard analysis of Robt Nicholson, esq. years ago!

Any drone drops of sheets and other paraphernalia will have "no" validity whatever to the DB Cooper placard analysis etc.

It's been done hundreds of times with leaflets during wartime.

My point is to see what happens to a normal placard vs the damaged one. I don't see any data on this? they are not going to react the same if I'm right.

I look at it as we are not in law enforcement so why are we investigating the case. it's be done for 40 plus years with all kinds of data and documentation?

I fail to see how this would not help in proving something one way or the other?
