Re: Интересно, и...
The Air Force hopes that the extra size should give it enough fuel and helium to stay aloft for as much as a week at a time at nearly four miles up. (Most blimps float at 3,000 feet or less.) Staying up so high for long is all-but-unprecedented. But it’s only a third of the proposed flight time for a competing Army airship project.
Хотят неделю, и есть другой проект, который должен три.
