So they used hypoxic training, plus xenon. But none of this indicates that the xenon was the decisive factor. Nothing in the story mentioned actual medical testing done.

The former special forces troops used xenon gas to acclimatise to climbing at high altitudes more quickly.

Kova juttu, kun sain kertoa lapsille tavanneeni Niiskuneidin / Knallin ja sateenvarjon Mildredin. Aila ja Lars Svedberg muistivat 30 vuoden takaa, kun kävin tekemässä omaan lehteeni juttua Knallien äänityksistä.

Nyt se lähti painoon! Kolmas romaanini Vain ajan kysymys (ilmestyy 12.6.). Äiti on jo luvannut ainakin kuunnella äänikirjan.

And the funniest thing? Kujau wasn't even a good forger. But people were greedy, and wanted to believe.
'It will be a great hoax in the history of mankind': How fake Hitler diaries fooled the British press
In April 1983, a British newspaper, The Sunday Times, claimed to be printing an extraordinary historical document. In fact, the forged diaries were an extraordinary hoax.

Six years ago, my life permanently became different - and for the better - when I became a real space historian. Enjoy my handiwork!

The Rocketdyne F-1 engine turbopump. There is a certain kind of elegance to it, don't you think?

Interesting thing in "The Phage" on #StarTekVoyager #StarTrek - they walk along a 'corridor' with portholes to reach Captain's dining roon, and it's obviously just the mess hall windows. Can't remember this being done in any other episode? Image via @trekcore.com , who are the best!

I'm watching #StarTrek VOY "Blood Fever" and this episode has not aged very well has it? B'Elanna gets sexually assaulted and nobody even cares?

PlutoTV has added #StarTrek Voyager onto streaming here. They keep translating away team as the Finnish equivalent of "Guerrilla team", which is hilarious.
