No more "Left Downwind"?

I managed five landings without rolling past the numbers with calm air
the
other day. Making really short AND smooth landings AND hitting the exact
aimpoint has proved elusive. I can usually accomplish any two but not
all
three. It gives me additional respect for the pilots demoing Helios at
OSH.

I can't imagine what flying something like that must be like. Very
challenging, it sounds like!


It is always difficult to get every bit of performance out of an aircraft.
Usually we make it easier by using approach speeds that are high and settle
onto the runway. To put it down on the first foot of pavement at the
absolute minimium speed is a challenge in anything.



I was
climbing in the Andes early in the year and then made an attempt on the
North side of Everest in the spring. I reached 25,000' without O2 and
then
bailed for a variety of reasons.

Um, isn't life pretty much unsustainable at that altitude without
oxygen?

Depends on what you consider unsustainable. The highest permanant
settlement is about 18,000'. Personally I felt that I was constantly
deteriorating above 21,000'.

How many months do you live at altitude, before climbing the
next 5,000 feet? In other words, as I understand, a healthy
person can climb, 5 to 10 thousand feet above their living
altitude before hypoxia become serious. If you live at
10,000 feet for 6 months to a year, your body adjust and
adapts to that pressure and oxygen levels, you then can
climb or fly higher. If you return to sea level you may be
"super charged" or even get sick for a short while until you
readapt.

In the 1940 and 50s, I understand it took many moths for
Everest climbers to portage several higher and higher base
camps, before the actual assault on the top.

You can ascend about 1000'/day It works out to a little less when you go
really high (above 20,000'). The only risk coming down is to avoid getting
dehydrated as you are prone to clots (this is a risk when at altitude too).
