Re: Hawaiian Airlines firms order for 10 787-9's plus 10 options

Hawaiian wanted more than 767? Maybe, but not by much as they only ever got A332s. A333 could easily make West Coast-Hawaii, but it appears HA manages their capacity. I personally don't quite understand - A332 is a heavy bird for its size when compared to 767-300ER, but it works for HA. The A332s ar...

Re: Why doesn't civil air cargo use planes like the Boeing C-17?

It's tough to find examples of military cargo lifters that found civil operators. I can't find any for G.222 or C-295. There were some (not many) for C-235. L-100 (civil C-130) has had a bit more success, but again it's fairly limited. Then you get into the range of Skyvan and Skytruck, which are mo...

Yes, I thought fuel tanks had to be drained before air transport. It's customary for other kinds of machinery. And I'm sure the pilots were thrilled to find out they had a cargo with fuel inside, that ended up sloshing around their aircraft while in flight. :shock: :hot:
