Weather balloons transporting thousands of packs of cigarettes have caused flight disruptions in Lithuania, as Lithuania's primary air hub was forced to close for an extended period when dozens of them entered the national airspace.
The airport closure led to the cancellation of 30 flights affecting thousands of passengers, with airport representatives alerting that further disruptions were possible throughout Monday.
Officials confirmed that twenty-five weather balloons were observed crossing into Lithuania from neighboring Belarus, with two of which ending up right above the aviation facility.
As many as 14 of the atmospheric instruments deployed throughout the weekend drifted across the metropolitan zone, which is situated near Lithuania's main urban center and close to the Belarusian boundary.
At least 11 balloons containing numerous containers of black-market cigarettes have since been recovered, though additional discoveries are expected, according to customs agents.
Although causing problems, officials emphasized that "Balloons with contraband - cigarettes from Belarus - are not unusual in Lithuania, Latvia, and Poland."
So far this year, numerous meteorological balloons have been documented crossing into Lithuania from Belarus, while approximately 966 had been documented the previous year.
Meanwhile, the north-eastern Podlaskie region, which also borders Belarus, has recorded more than numerous instances in which smuggled items were delivered from its neighbor using the meteorological equipment.
Regarding inquiries concerning why criminals use a technique that proves highly susceptible to weather elements rather than easier to manage drones, representatives elaborated that "Meteorological balloons are basic instruments used by smugglers - they are cheaper than drones for moving tobacco products from Belarus."
Officials added that "Our services' aim is to confiscate the maximum possible volumes of smuggled items and to detain organisers and perpetrators so that these practices become unprofitable and present no risk to commercial air travel."
The recent incidents occur during an era marked by increased concerns in Europe following multiple unmanned aircraft violations that have resulted in flight interruptions across European nations.
Similar occurrences in adjacent nations have caused EU officials to speed up talks about improving airspace protection throughout European airspace.
