Instead of building models based on experimental engineering, Boeing had been hard at work developing their bomber and now had versions ready for production far better than would have been possible otherwise.
Istedet for at bygge fly baseret på eksperimentel teknik, havde Boeing været nødt til at arbejde hårdt for at videreudvikle deres bomber, og havde derfor bedre versioner langt mere klar til produktion end der ellers ville have været muligt.
