Reminds me of the conversations between Pan American's Juan Trippe and Boeing's Bill Allen described in Skygods [0] (don't have exact quote but this blog [1] is close enough).
> With the head of Boeing as captive audience, Trippe laid out his vision for an airliner that would multiply the astounding success of Boeing’s 707 by adding capacity for more than twice as many passengers. Allen, already sitting on the substantive plans of Boeing’s proposal for the USAF CX-Heavy Lift System (soon to be won by the Lockheed C-5 Galaxy), was more than interested.
> The meeting is supposed to have concluded with his famous line ‘If you’ll buy it, I’ll build it.’ To which Trippe replied ‘If you build it, I’ll buy it’.
