The Final Victory Weapon [Portuguese]

A photograph of a four-engine US bomber with a star on the wing, seen from above over fields, sits above a Portuguese text block, a US flag and a portrait of President Roosevelt. The text gives only the bomber's strengths and US production figures (card-stacking), and the flag and presidential portrait lend national authority (transfer).

A ARMA DA
VITÓRIA DECISIVA

Os raids de bombardeio de longo alcance realizados pela R.A.F. demons-
tram que a "Fortaleza Voadora" americana é a arma que os agressôres
não previram. Atacando de uma altitude de 12.300 metros (os novos
modêlos vôam ainda mais alto) mantêm-se fora do alcance de qualquer
fogo anti-aéreo, ou dos aviões de defesa que mais alto possam subir.
Quatro importantes fábricas dos Estados Unidos estão produzindo agora
êstes formidáveis bombardeiros, que serão igualmente manufaturados na
grande nova fábrica que Henry Ford fez construir especialmente para tal
fim. A experiência profissional na América e as suas vastas possibilidades
permitir-lhe-ão produzir "Fortalezas Voadoras" na base da produção em
massa. Programa de produção inicial dos Estados Unidos: 500 por mês.

THE WEAPON OF DECISIVE VICTORY

The long-range bombing raids carried out by the R.A.F. show that the American "Flying Fortress" is the weapon the aggressors did not foresee. Attacking from an altitude of 12,300 metres (the new models fly even higher), they stay out of reach of any anti-aircraft fire, or of defending aircraft that can climb highest. Four important factories in the United States are now producing these formidable bombers, which will also be manufactured in the great new factory that Henry Ford had built specially for the purpose. Professional experience in America and its vast possibilities will allow it to produce "Flying Fortresses" on a mass-production basis. Initial US production programme: 500 per month.
