You are ignorant that is clear, and can't read either:


Am I? What have I written that you believe is incorrect?



The Brabazon 1 had a pressurised cabin, hydraulic power units to
operate the giant control surfaces, the first with 100% powered
flying controls, the first with electric engine controls, the first with
high-pressure hydraulics, and the first with AC electrics.

All eventually adopted by all planes.


It wasn't the first with a pressurized cabin or powered flight controls, and
100% powered flight controls isn't such a good idea. It wasn't the first
aircraft with hydraulic systems, using a higher pressure than it's
predecessors is hardly ground-breaking. As for electric engine controls and
AC electric systems, so what? Even if it was the first aircraft to have
them there was nothing ground-breaking in putting them in an aircraft.



It did!


Boeing designed an airplane with skin four and one half times as thick as
the Comet's to resist tearing. It had titanium tear stops welded to the
interior skin. They specified round windows and spot welds reduced the use
of rivets. The Boeing board approved this design on April 22, 1952, ten
days before the Comet began passenger service and a year and ten days before
the first Comet disintegrated over India.

So, if the lessons of the Comet with regard to metal fatigue influenced the
design of the 367-80, it means de Havilland and BOAC knew about the Comet's
flaws even before the first one entered service.



See above.


I saw above. Who operated an airliner similar to the Brabazon?



All of them, even American.


Yet you cannot identify a single type.
