Hydrogen as an aircraft fuel source ?

It is investigative journalism and as everyone knows you don't need to be a scientist to do that.

Well then don't call yourselves the "Union of Concerned Scientists" when most of you are not. Make it the "Union of Concerned Analysts" which most of you are, or the Union of Concerned Investigative Journalists" which all of you are not. But of course those names don't add that veneer of respectability.

I'm not disputing the figures, but you are hardly likely to get an unbiased view from that "union". They aren't going to tell you, for example, that coal mining (0.15 deaths per million production hours) is only marginally more dangerous in the US than other forms of mining (0.1 deaths per million production hours) and that the industry that kills most workers is fishing. They aren't trying to shut iron or copper mining down. Or get us to stop eating tuna.

I concede that you have a valid point.

I don't think their statement is a matter of bias. The figures simply show that coal mining is not scott free in terms of human life and health. On the face of it those mining figures are probably an acceptable risk but they are not the main reason we are moving away from coal. It's after it's burned the trouble starts. The rest of the article is food for thought.

This means coal mining is 50% more dangerous than other mining.

If the profitability of my business increased 'marginally' by 50% over current figures I'd be very happy.

Full computer drive cars and trucks will soon be in daily usage so i would suspect that the 'refuelling', be that petrol, diesel, hydrogen, moonbeams, whatever, will be done automatically with no human involvement. With the computer cars accidents of all types will be dramatically reduced so the increased dangers of hydrogen may not factor into peoples concerns. As to aircraft usage...?
