Re: Countries that don’t have their own airline

Most African countries have no commercial airline of their own. At the same time they tend to be de-facto islands because they cannot be easelly reached by any surface vehicles like trains or lorries. Those are fly-in-fly-out countries without an own airline. OK, I decided to run down the list here...

Re: BEA : EgyptAir MS804 crash caused by pilot smoking

Are the masks supplied with 100% pure O2? I thought the human body can't handle pure O2 for extended periods? I do not know, but 100% FiO2 is toxic owing to the corrosive/oxidizing nature of oxygen. In addition, 100% FiO2 would be very dry since it would, by definition, be 0% humidity. However, eit...

The big advantage of hydrogen (notwithstanding how it is produced) is no CO2 emissions.
