You aren't going to see lightning flashes or anything. The timezone boundaries are completely artificial and arbitrarily defined; they are not connected to some essential physical characteristic of the planet. The location of the zones is based on the location of the Prime Meridian, zero degrees longitude, which goes through Greenwich England If you change zones, you simply reset your watch and other timepieces you have with you.
On a longer flight it makes sense to set your watch once, and I suggest at the beginning of the flight-- so you can start getting adjusted to the timezone you are going to. Do it the way that it is comfortable to you. The farther away from your own timezone you go, the more different will be the diurnal (daily) cycle that your body will experience.Travel agents and flight attendants will have hints to help you adjust.
If you cross the dateline it gets a little more complicated but it is manageable.
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.
