Talk:UK firm designs hypersonic passenger jet

The image used lacks fair-use rationale and it should be a low resolution version. --SVTCobra 18:02, 6 February 2008 (UTC)

I'll sort that out. --Mephiles 19:02, 6 February 2008 (UTC)

Does wikinews have a fair use rational template? --Mephiles 19:07, 6 February 2008 (UTC)

Yes, but I see you already found {{Non-free use rationale}}. Cheers, --SVTCobra 23:22, 6 February 2008 (UTC)

Australia

What does "It would be able to reach Australia in just five hours" mean? From where? Wikidsoup 20:54, 6 February 2008 (UTC) I would assume England, but that should be clarified. Wikidsoup 20:55, 6 February 2008 (UTC)

I sorted it out ;) Thank's for pointing that out. --Mephiles 22:23, 6 February 2008 (UTC)

Nitrous Oxide

I edited the last part about the jet being environmentally friendly. Note that nitrous oxide, which the jet emits, is a greenhouse gas. I would like to see some discussion as to why this is any better than giving off CO2. If we don't have a source for this, it's not worth mentioning I think. Wikidsoup 20:59, 6 February 2008 (UTC)

"It would operate on liquid hydrogen, which is more ecologically friendly as it gives off water and nitrous oxide instead of carbon emissions." - Times Online. You do make a good point, however. --Mephiles 22:24, 6 February 2008 (UTC)

Wikipedia's nitrous oxide article says this: Unlike other nitrogen oxides, nitrous oxide is a major greenhouse gas. While its radiative warming effect is substantially less than CO2, nitrous oxide's persistence in the atmosphere, when considered over a 100 year period, per unit of weight, has 296 times more impact on global warming than that per mass unit of carbon dioxide (CO2). So I guess it would come down to how much N2O it gives off compared to how much CO2 a conventionally powered craft would give off. It could be better or it could be worse for the environment. --SVTCobra 22:38, 6 February 2008 (UTC)

Nitrous oxides are produced in flames because the atmospheric nitrogen burns with the atmospheric oxygen; all combustion produces nitrous oxides. So the aircraft wouldn't necessarily produce any more nitrous oxide than other aircraft, and it wouldn't produce in and of itself any CO2 at all. It's not one or the other.Wolfkeeper 00:51, 7 February 2008 (UTC)

My first article

This was my first article on Wikinews. Thanks for the help everyone :D --Mephiles 15:44, 7 February 2008 (UTC)
