At first glance it is not very attractive, but this infographic from The Guardian is certainly striking in contrasting the empty skies over Britain due to the volcanic ash against the business as usual previous day’s travel.
It is a sight apparently not seen since World War II.
And it is pretty staggering to be reminded of how many planes are in the sky at any one time (especially given the Polish tragedy this week). That’s a lot of machinery, a lot of decisions being made, a lot of room for human error… it’s a wonder airflight is as safe as it is!
BTW, what’s with that plane south of Ireland? Is he lost?
Effective graphic? What do you think?
