Harriers hover. F35s hover. Harriers have machine guns. F35s have machine guns. Harriers are flat-looking jets. F35s are flat- looking Jets.
See the similarities?
Not all F35s are capable of hovering.
Neither plane carries machine guns.
You don't know what "flat" means because neither of those planes are flat.
even as it seems, they both were meant to do the same job.
The P38 Lightning of the second world war was a ground attack plane, are you implying that it is interchangeable with modern aircraft simply because it fulfilled a similar role?
