For anyone whose travel plans have been in disarray in recent days, the story of Icarus is one that may come to mind.
Icarus on Wikipedia
Safe flying is something we humans may have come to take for granted in our instant 21st century world. Fast food and fast travel are creations we demand to make our ambitions a reality.
The first successful human flight took place in 1783, a year when an Icelandic volcano changed the course of history.
As a well informed traveller, you will by now be aware of at least something of the history of Icelandic volcanoes. I have never been to Iceland but I have been in volcanic regions elsewhere.
Here is a link to one of my Quieter Living blog posts, mentioning one of my experiences near a volcano in South America.
I almost experienced a volcanic eruption at Mount Ruapehu during a snowy afternoon in New Zealand in 1994. On our way to the volcano, a driver coming the other way stopped our rented campervan and suggested we turned back. My husband and I accepted his advice - the other driver was a vulcanologist.
