Sounds like a nice idea, but unless you have plenty of time for service or only offer this in first/business class, I don't see this as being very practical. In order to fill the cups, the flight attendant would have to return to the tap every time someone wanted a beer. Plus, a tap can only offer a limited selection.
Personally, I'd rather have a wide range of choices in cans than take my chances with what they might offer out of a tap.
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.
