seriously? you think that militaries make their procurement decisions based on airshows - and on what the general public think?People will keep doubting its capabilties until they actually see it. whats needed is to put the aircraft out there at shows like Farnborough and dubai/Singapore. maybe make a mix f-22/f-35 show of force at red flag show people its capabilites then you will get silence.
we employ professionals because they know their craft.
if we went the general public route we've had an absolute force mismatch and a capability more useful for warhammer rather than considered warfighting
