On the night of 22–23 March 2026, Vilnius International Airport (EYVI) suspended operations after radar detected signatures characteristic of contraband weather balloons from the Belarusian direction. This was the fourth balloon-related closure of Vilnius Airport in 2026. The previous incident had been recorded just seven nights earlier, on 15 March 2026. No injuries were reported; crew and aircraft scheduling disruptions caused minor delays into 23 March.
The March 22–23 closure occurred the night before a stray Ukrainian military drone crashed near Lake Lavysas in Lithuania's Varėna district on 23 March 2026, undetected by Lithuanian radar. The overlap of a balloon airspace closure and a drone crash in the same 24-hour period concentrated attention on the eastern border from two directions simultaneously.

What AirVeto's wind layer shows for the event window
The wind layer on the map displays the 700 hPa (approximately 3,000 m) wind field over the Lithuanian-Belarusian border region during the closure window on the night of 22–23 March 2026. This pressure level corresponds to the primary cruise altitude for contraband cigarette balloons crossing from Belarus: high enough to clear radar ground clutter, low enough that helium leakage brings the payload down over Lithuanian territory before the balloon drifts beyond the target zone. At this altitude, easterly flow within AirVeto's 85-degree border-normal threshold creates the inflow condition that places the Vilnius approach corridor in the drift path from the Belarusian side. The Open-Meteo historical model is described on the methodology page.
Simultaneous pressure from east and south
In the same 24-hour window as the March 22–23 balloon closure, a stray Ukrainian drone was descending through Lithuanian airspace to crash in the Varėna district, roughly 100 km southwest of Vilnius. That drone had been diverted from a strike on Russian oil infrastructure by Russian electronic warfare before crossing into NATO airspace. The two events are unrelated in origin: the balloons are a Belarusian hybrid operation; the Varėna drone was a Ukrainian military platform gone off course. But their coincidence on the same overnight period illustrated how the Baltic region's airspace was simultaneously contending with threats from the east and south in March 2026.
Part of the 2026 closure sequence
Lithuania had intercepted at least 45 balloon probes carrying contraband cigarettes from Belarus in the first quarter of 2026 by the time of the March 22–23 event. The political pressure on Vilnius and Brussels was intensifying: Lithuanian politicians were openly describing the launches as a directed hybrid campaign, and calls for EU sanctions against Belarus specifically citing the balloon operations were gaining support.
The March 22–23 closure was followed by the longest disruption in the 2026 sequence: the 9–10 April 2026 closure lasting close to seven hours. The Vilnius Airport location hub covers the full record of closures and wind reconstructions in the AirVeto archive. The Lithuanian smuggling-balloon category page is Kontrabandos balionai.
