Is it possible to fly from one sector to another?

From looking at the galaxy map, it seems that you should be able to transit from one sector to another without using jump gates, accelerators or highways. When I try flying to the edge of a sector, though, it seems that I can approach the edge but never cross it.

Is it possible to fly from one sector to another directly or are jumps required?

Solution 1:

Sadly, it's not possible. Travelling between sectors is still done by "Jump Gates", like in X3.
