To fly long distances economically, the Fw 200 was designed to cruise at an altitude of over 3,000 m (9,800 ft) - as high as possible without a pressure cabin.



The HE-111 was a medium ranged bomber, but in rare cases they added extra fuel tanks to the wings so it was capable of flying for a longer period of time.



B-17's were heavy bombers and was capable of very long distance travel with a full load, but when it has no extra weight added on, it's one of the most long range bombers of it's time (Not the very best, remember that).
