How long do balloons and blimps stay inflated?

In good weather, advertising balloons and blimps will lose between 1% and 3 % of their volume per day. To prevent damage balloons should be flown clear of poles, signs, trees etc. Repair service not available. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
