The day before NASA prepared for the final launch of Atlantis, Mercy Air also was on a mission, to explore strange new heights and to boldly go where no Mercy Air aircraft has gone before.

We had some issues with the turbo charging on the C-210 and needed to do a test flight to verify that things were working as they should. This basically involved flying it at a certain climb power setting and noting what happened.

Towards the end of the test I took a couple of pics. This one shows us doing 500ft/min rate of ascent at 170 knots ground speed - not too bad for a 210.
But a quick glimpse at the outside air temperature shows a chilly 0 deg F or getting on for -20 C.
The reason for that is found with a closer look at the altimeter, not 11500ft but 21500 ft. That's just over four miles high.And a quick look out of the window...
It was well chilly up there wearing just shorts and T shirt and it only occurred to me to close the air vents on the way back down. More important was though was to use a little supplementary oxygen, which you can just spot in the next pic.
So, I didn't find any new life or new civilisations up there and I was only gone an hour, rather than the five years it took the Starship Enterprise.

If you are an airline pilot or Himalayan mountaineer, please feel free to be quite unimpressed by all this. But for a little plane pilot like me it was a very novel experience.

Very impressed and more than a little envious.
