Meteorological devices containing thousands of packs of cigarettes have caused flight disruptions in Lithuania, as the country's main airport was forced to close for several hours when dozens of them floated into the country's airspace.
The temporary shutdown led to 30 flight cancellations affecting six thousand travelers, with airport representatives alerting that delays might continue throughout Monday.
Authorities reported that twenty-five weather balloons were observed crossing into Lithuania from the border with Belarus, with two balloons ending up right above the aviation facility.
Up to 14 of the atmospheric instruments launched over the weekend floated over the Vilnius area, which is situated near Lithuania's primary metropolis and adjacent to the frontier with Belarus.
No fewer than 11 balloons carrying eighteen thousand packages of illegal tobacco products have since been recovered, though this number could rise, according to border security officials.
Despite the disruption, representatives clarified that "Weather devices carrying illegal goods - tobacco products originating in Belarus - are common occurrences in the Baltic region and Poland."
Since January, over five hundred weather devices have been observed infiltrating Lithuania from Belarus, while approximately 966 had been noted during the prior year.
At the same time, the north-eastern Polish territory, which similarly neighbors Belarus, has registered in excess of numerous instances in which illegal goods were transported from its neighbor using the meteorological equipment.
In response to questions about why criminals use a approach that remains especially affected by weather conditions rather than more controllable drones, representatives elaborated that "Weather devices are simple mechanisms used by contraband transporters - they are more economical than drones for carrying smoking materials from Belarus."
Officials added that "The objective of our agencies is to capture the greatest possible amounts of illegal goods and to arrest masterminds and participants so that this activity become economically unsustainable and do not pose risk to commercial air travel."
Such border infiltrations occur during a time of increased concerns in Europe following multiple unmanned aircraft violations that have created aviation problems across the continent.
Recent incidents in adjacent nations have prompted European leaders to accelerate discussions about strengthening air defences throughout European airspace.
