Once upon a time when I lived in Sydney,
Australia, I was standing down at the beachfront one night looking out into the
dark distance of the Pacific Ocean when a single, plaintive light came twinkling
into existence on the horizon. The lonely light gradually drifted closer and
grew in strength, and without a great leap of recognition I soon realized that
I was watching a late evening flight arriving in from New Zealand. Covering
those vast distances, even at the jet-powered speed of a commercial airliner,
there was something slow and sad about the light drifting wistfully closer.
I don’t know about you, but for me there
are few more humbling sights as a human being than to look out on a clear night
and see the silent winking of an aircraft’s lights, especially when it’s high
overhead and as it makes its way into the distance. There is something about
the scale and distance of the immense and powerful aircraft covering its
monumental journey, whilst looking no more than a speck in the sky, that brings
me for some reason very much in touch with the fragility of life, and the true
tininess of human beings in comparison with the vast space of our planet and
its atmosphere. Even though commercial airline flight is clearly a widespread
commodity in many parts of the world these days, we can always imagine that the
people on the plane have some special trip ahead of them, some work meeting, or
are perhaps heading back to their families and friends and the familiarity of
home.
I couldn't resist choosing this particular picture of an aeroplane (it's not even an Austrian airline). The work of RuthAS under a Creative Commons Licence. |
We recently had a visit from a relative
from Germany who is a commercial airline pilot. He was stopping over ready to
pilot his flight the next day from a nearby airport, and having some free time
decided he would come and see us and visit my grandfather, his great uncle.
When he was growing up, he would see my grandfather on visits to my Austrian
grandmother’s home village in the mountains. There they
spent long and happy hours in each other's company, though as I understand it, the ambition to become a pilot did not come until many years later. Fast-forward to 2015, and there we were sitting in my grandfather's home in England, with a living
breathing pilot telling his wide-eyed audience about the wonders of flight and
the true realities of the career of a pilot, the good and the bad. We were of
course, suitably starstruck.
During that meeting he suggested we get
hold of a cheap plane-tracking app, easily downloadable from the app store or
whatever, for a bit of fun to track him back home the next day. I went for PlaneFinder, but in reality I see there are many available, and (even normal) people
use them to track relatives flying in for a visit.
There are more planes than I thought. |
Apart from happily tracking our
relative back home the following morning, directly over the roof of Grandad’s
care home, my current usage is far more nerdy than tracking my rellies. If I’m walking through
the park or on my way to and from work, and see a vapour trail tracing across
the sky, I will look it up. I find out which airline and aircraft is flying the
journey, and where the people on board are headed (sometimes bringing back
unpleasant memories of long-haul flights to and from Australia). I see how long
I can keep sight of a particular plane as it soars into the distance. It helps
me to visualize something that has often captured my interest and imagination:
the true scale of the island upon which I live. The other night I just about
managed to watch a plane from passing mostly overhead to the point where it
passed the coast and headed out over the North Sea, before I lost track of it
in the haze.
They say the aeroplane has shrunk the planet, but I think in a way
it can also help to teach us how big it really is compared to us, or rather how
small we are in comparison to it. As a physicist I appreciate anything that helps me to make these visualisations.
