Can a cabin crew work in both A330 and B777?

It depends on what country you live in. There are some countries that do not allow, or severely restrict the ownership of private aircraft. Even in the countries where aircraft ownership is not restricted, there are government regulations preventing the operation of aircraft (including helicopters) in certain areas, below certain altitudes, or without establishing radio contact and obtaining permission from the controlling agency.

So no, you can't just fly freely, anywhere, any time. And many local restrictions are placed upon the use of helicopters, especially in urban areas, so it is often not possible to legally take off or land in the majority of places including your own property. Bottom line NEVER believe what you see on TV or in movies regarding aircraft.

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.
