  1. "There is no radar over the north Atlantic" This is finally changing. The iridium satellite network received an upgrade to be able to input transponder extended mode S data, which includes GPS data from airplanes. This means that virtually all "dark" spots in the world are now covered with what is sometimes called "active radar", that is, aircraft that self report their position instead of waiting to be swept by radar. This system was partially advanced by the idea that it would make Malaysian airline type accidents less likely (aircraft disappearing over ocean regions). However, it has long term consequences on aircraft spacing in over ocean routes. You can put flights closer together if you know exactly where they are.
