If the mountain Katla, which is only a few miles to the east of Eyjafjallajokull starts erupting, it will make this erupton look like a "campfire". This is a real possibility now because eruptions in Eyjafjallajokull mountain have been known to trigger eruptions in mount Katla. If that happens, we will not be having debate about if it is safe to fly in the UK like we do now, it will most likely not be safe or even clear enough to go VFR
That is what we all fear, if history repeats itself, flying will be the least of our worries
