In an unprecedented lock down of European airspace, most of the major European airports shut down all service as ash from the Icelandic volcano continued to cover most of Europe. European airlines, losing approx. $200M per day cried foul on the mish mash of European regulators who control the airspace, and demanded for a unified EU approach. Munich airport has largely been non-functional for three days. So it was a bit of a shock to see this blimp flying all over Munich for the past few days. European airlines are expected to reach 50% capacity by Thursday, and European governments are enlisting a broad band of holiday companies to leverage their airlines to bring travelers home.
