Likely a case of airlines not wanting to have the responsibility and deal with the aftermath if it does spread inflight.

Re: Wing length and economy of scale in aircraft manufacturing

Not an engineer, but I’m pretty sure that the 380 wasn’t able to have the wingspan that it should have because it had to fit into existing gates at airports. Therefore it was kind of doomed from the start, which is why they don’t make ‘em anymore. If it didn't have the wingspan it needed then it wo...

Re: Cargo Freighters operating cost comparison

Lease cost vs utilization is the big one. A 777 might have lower fuel burn but that doesn't weigh up against the extra non-operating costs when it's only in the air for less than 30 hours a week.

There's a reason a lot of cargo airlines are picking 747s out of the desert.
