According to LRT (Lithuania's national broadcaster) and Pravda Lithuania, a Belarusian smuggling balloon triggered the ninth disruption of Vilnius International Airport in 2026 on the night of 12β13 May 2026 (23:16β00:16 UTC). The airport was closed from 02:16 to 03:16 EEST, lasting exactly one hour. A total of 128 passengers were affected; one flight was diverted to Copenhagen. LRT's reporting explicitly characterised the event as "the ninth disruption" of the year β the first time Lithuania's state broadcaster used a running count, signalling that the accumulation of balloon-induced closures had become a documented operational pattern.

LRT's "ninth disruption" count β what it signals
The explicit "ninth disruption" count from LRT is the key detail of this incident. It establishes that by mid-May 2026, Vilnius airport had experienced nine separate balloon-induced closures or disruptions in 2026 alone β an average of roughly two per month since January. Earlier incidents in the series include the February 2026 closure (the second disruption of the year), making the May 13 event the seventh closure to occur in the MarchβMay window.
LRT also noted that the same night β 13 May 2026 β saw a separate Kaunas-Ε anΔiai balloon event, confirming that the May 13 activity involved at least two simultaneous balloon crossings over Lithuania: one affecting Vilnius airport's approach corridor, one over Kaunas.
02:16 to 03:16 EEST β a one-hour pre-dawn closure
The precise window (02:16β03:16 EEST) places this closure in the deep overnight period, when Baltic balloon crossings most commonly occur. Belarusian smuggling balloons are typically launched before midnight, crossing the border in the pre-dawn hours when ground teams in Lithuania can recover cargo without daylight exposure.
The one-hour closure affected 128 passengers β a small number compared to the February closure (~700 passengers), consistent with the pre-dawn timing when fewer flights are airborne.
One flight diverted to Copenhagen
The diversion to Copenhagen, rather than to the closer Baltic alternatives (Riga, Kaunas), indicates the diverted aircraft was a longer-range connection already committed to a westward track, making Copenhagen the operationally appropriate diversion rather than a short-hop Baltic alternative.
The same night: Kaunas-Ε anΔiai balloon event
LRT's reporting confirmed that 13 May 2026 was a multi-event night. A separate balloon was tracked over Kaunas-Ε anΔiai β the military airfield zone south of Kaunas β simultaneously with the Vilnius airport closure. This two-simultaneous-event night represents the same operational pattern documented in Poland, where multiple balloons are launched in a single window to probe air-defence response times and split monitoring resources.
Wind layer β 700 hPa over Vilnius on 12β13 May (pre-dawn)
AirVeto's wind reconstruction covers the 700 hPa pressure level (approximately 3,000 m) over the Vilnius approach corridor during the 02:16 EEST window of 13 May 2026. The embed above renders the wind field; methodology is described on the AirVeto methodology page.
