BTW, dirigibles for short flights and long flights makes more sense, especially where cargo is the task. The top-side could be fitted with solar panels and the blimps travel above the clouds, to assist the batteries.
Except dirigibles have an unfortunate tendency to be turned into scrap metal by heavy winds. See our own experience with the USN’s dirigible aircraft carriers. They all wound up heaps of wreckage on the ground after heavy winds. And one in the ocean, the whole crew drowned because they weren’t issued life preservers.....
