-
This profile is the model
of a wing section.
-
It's called a wingspan.
-
And this, in particular,
is called Gottinga 398:
-
is the wing section
of this small tourist plane.
-
The wing is pushed into the air,
-
which divides at this point,
which is the leading edge,
-
and creates that magic that's called lift.
-
And so we trivialized dozens of years
of aerodynamics studies
-
in a split second.
-
This is true for both small
and large aircraft:
-
so, for example, we can go
to an exotic place, on vacation,
-
thousands of kilometres away
with a few hours flying -
-
of course, when possible.
-
Increasing the angle
between the wing and the air flow,
-
you can have a lot of lift
-
even when the wing moves
at a relatively slow speed,
-
how it happens - how it must happen! -
during landing and take-off.
-
But, there's a but:
-
if the angle increases
beyond a limit angle,
-
which is called critical angle,
-
a phenomenon occurs whereby the lift,
sometimes suddenly, stops.
-
We give a name to many phenomena:
-
and this, which is important,
as you can guess,
-
makes no exception.
-
And in Italian, we call it
"Stallo" [Stalemate].
-
What a strange word the stalemate is.
-
It is said: "The formation
of the Government is stalled";
-
"The meeting came to a standstill."
-
But also in more trivial things:
if we are on a diet,
-
"The loss of pounds has stalled."
-
We associate the word "Stallo"
with immobilism, with non-action:
-
yet, if a wing has a lift, and stalls,
-
suddenly it can only do what it can do:
-
that is to fly ballistically
towards the ground,
-
fall or something.
-
The English use
a very similar word, "stall."
-
Spanish people say "perdida" instead
-
which is a term that evokes
something much more serious.
-
The Germans, who are always very accurate,
-
they call it "Strömungsabrisse",
which means "demolition of the flow":
-
very technical.
-
All in all, I prefer
the term we attribute.
-
I didn't show up: I'm an astronomer,
I build telescopes,
-
tools that I launch into space,
at the conquest of planets or comets;
-
or that we mount on telescopes
-
in the most hidden places on our planet,
-
for example on top of the Hawaii Islands
or the Canary Islands,
-
or in the desert of Chile,
Arizona or California.
-
For work, whenever possible,
-
I move a lot with commercial traffic.
-
And when the plane,
until almost twenty years ago,
-
has some modest turbulence,
-
I usually get nervous, I start sweating,
-
open the air vent;
-
and I begin to express,
perhaps aloud, my opinion
-
that maybe it isn't worth the risk
-
for the mirrors, or the lenses,
that we're trying to study.
-
And of course, my colleagues
don't miss an opportunity to gloat,
-
pointing out
-
that my expressions,
sometimes very colorful,
-
are at odds with statistical evidence
-
that flights, transports
by commercial plane,
-
remain one of the most
statistically secure systems.
-
And so happens what
I couldn't have foreseen either,
-
and that many friends
would not have suspected at all:
-
in 2004, in a summer
of complete loneliness -
-
let's say unlucky in love -
-
I sign up - like this,
just to do something new,
-
something strange,
something life-changing,
-
I take flying lessons,
and it's a revelation to me.
-
Looking at the world from above
is a fantastic, magical thing;
-
I buy an old tourist plane right away,
-
with two partners,
-
with which we spend
more time fixing it than flying it.
-
Besides, I think with that little plane
-
we never left the Mugello Valley,
-
from which we had our first flights.
-
And all the people who come to this world
-
ask, perhaps frightened, what happens
-
when the engine that moves these planes -
which is very small - shuts down.
-
The plane becomes a kind of glider:
-
it's not much of a glider,
but it's what we need right now.
-
And technically,
-
you can even land the plane
in a tiny square of land.
-
In the course, this manoeuvre -
simulated, but not so much -
-
although with an instructor at your side
ready to handle the situation,
-
is performed over and over again.
-
Strange as it may seem,
-
most fatal accidents in this world,
-
does not occur due to lack of propulsion,
-
which, however, is now
an extremely rare phenomenon,
-
apart from cases of gross errors,
-
such as running out of fuel;
-
but rather, because
during the slow flight,
-
maybe just in the take-off
and landing phases,
-
you can't keep between you
and the stalemate
-
all those intervals,
those obstacles, that distance
-
that they teach you obsessively,
during the course, to keep.
-
Because stalemate can also be
something natural:
-
you're flying, and maybe
one of the two wings stalls;
-
and if, for example,
you stall with the right wing,
-
the plane suddenly starts
pointing its nose
-
in the opposite direction
to the one you're flying:
-
can be very confusing.
-
Moreover, the stall can be solved
in a relatively simple way:
-
you just deliberately
crash the plane for a few seconds,
-
so that this one picks up speed
and starts to have lift again.
-
This is an unnatural move
that is taught to the pilot
-
so that you avoid,
-
when the aircraft is losing altitude,
-
to try to put your nose up,
-
which would further worsen the situation:
-
but rather to promote, second it.
-
It is an unnatural move,
obsessively taught to the student,
-
and which is summed up in the phrase:
"In flight, speed is life".
-
And so, we get to the stall date,
-
which in my case happens at 12:17
on July 17th, 2011.
-
The appointment is not in Samarkand,
but in Massalengo, near Milan,
-
where I am a passenger on the plane
of a friend of mine who is flying.
-
I was an instructor at the time,
-
but it's just a fun flight.
-
It happens because we don't prevent
a series of mistakes,
-
and we only rush to fix it
at the last minute.
-
Because in these little planes,
-
although they are slower
than commercial traffic,
-
actually, flying quite low
compared to scheduled aircraft,
-
there's no time to review
the footage of your life,
-
like we hear in passengers
-
of a plane that undergoes
some emergency.
-
Plus, in that case
someone else is flying for you,
-
and this is certainly not the case here.
-
With these little planes,
everything happens damn fast:
-
the stalling plane,
the crashing plane on one side,
-
me returning to command -
-
all these planes have dual controls,
as in driving schools;
-
the aeroplane regaining speed, lift;
-
and yet, unfortunately,
at that point we are very low:
-
we have trees in front of us.
-
And the words resonate in my ears
-
that the instructors have told me
a thousand times,
-
and that I myself
keep telling my students.
-
That is, when we are slow,
and we have an obstacle before us,
-
trying to fly over it,
getting the plane up even higher,
-
could be hopeless.
-
Much better to get into the treetops,
-
rather than running the risk
of stalling in front of it, or over it.
-
I meditated for a long time
-
if I had the opportunity
to acknowledge this mistake earlier,
-
and on my obviously erroneous assessment
-
that verbally alerting my flightmate,
-
who was in charge,
-
was sufficient to solve the issue.
-
There's nothing to do:
-
when you're 300 feet off the ground,
with a stalled wing,
-
you must not think, you must act.
-
And so I did.
-
We went into the treetop,
-
the crown dampened the speed of the plane,
-
a trunk has ripped
one of the wings apart,
-
we landed upside down
on the edge of a canal.
-
Damage to aircraft tanks
-
made the gasoline leak out,
so the plane didn't lit.
-
We came out in a bit of a trouble:
-
I was almost unharmed,
-
my flight companion had the need
-
of a few weeks of hospital,
-
a few months to recuperate.
-
But we both flew back together
as soon as we could.
-
Because, by stealing a term
from the horse racing,
-
"Saddle hurts, saddle heals":
-
so, even though I had to use violence,
-
I tried as soon as I could to fly back.
-
Of course, the world has changed,
not just in the way we fly.
-
Now I'm doing it in a much wiser
and much more rational way,
-
perhaps obsessively analyzing
weather conditions
-
or the conditions of the runway
where I must land;
-
or by continually testing me
in marginal conditions,
-
but in a safe situation,
-
to avoid having to do it suddenly,
-
in the face of a genuine emergency.
-
And so, you learn that being defensive
-
doesn't necessarily mean
taking a step back,
-
but rather to be able
to have the awareness
-
of when taking a step back
is the only possible way.
-
So, don't stop flying, absolutely:
-
on the contrary, almost fly more.
-
But to do so with an awareness
of that information
-
that until that moment
you had only read in the books,
-
had been told to you
by a lot of other people -
-
on the other hand, we cannot make
all the possible mistakes in our lives -
-
and all of a sudden seep into your pores.
-
And the whole world suddenly takes
on a completely different flavor.
-
Suddenly, everything becomes a bonus,
everything becomes free;
-
and so you find yourself celebrating
the anniversaries of this rebirth.
-
Soon it'll be ten years from now,
-
and I can't wait to celebrate adulthood.
-
And learn to try to do
-
those things you left out, thinking
you were going to do later,
-
and risked remaining pure fantasies.
-
You understand the significance
of doing, compared to discussing,
-
how easy it is to fall into unnecessary
and endless discussions,
-
that are different from achieving a goal,
-
from achieving a result.
-
And the accident as a metaphor
for so many things that happen in life.
-
When you have to make a quick decision
to do something "wrong,"
-
like throwing yourself into the treetops,
-
because you deem it the lesser evil,
-
and the irrelevance
of the endless discussions
-
that you can do, maybe sitting in a bar,
-
compared to what was more or less
appropriate to do.
-
And also the inevitability
of what's beautiful.
-
The incontrovertible fact
that flying on an aircraft,
-
and look at the world from above,
-
or look at the sky with a telescope
that's never been built before,
-
conceal such beautiful things inside them
-
to make this drive incredible,
-
and prevent us
from not continuing to do so.
-
Were they, were we lucky?
-
I just acted in the way that,
in flight manuals,
-
can be found under
"Recovery of the stalemate"?
-
Maybe I should have hung
the cloche on the nail.
-
as they say,
-
so as to put in the most abject way
between me and the source of the risk
-
a distant root, in order
to simply prevent this risk?
-
I don't know.
-
This second chance
-
accompanies me, invisible,
for almost ten years,
-
and I'm not sure I used it the best way.
-
But I'm sure, incontrovertibly certain,
-
to keep trying to do it with all my will.
