Around 09:00 local time on 31 January 2026 (07:00 UTC), a twin-envelope contraband-smuggling balloon, a paired-balloon design built to carry a cigarette payload and then gradually leak helium and descend, was photographed over the Šventoji coast on the Lithuanian Baltic seaboard, at the western edge of the country. It had crossed the full east-west extent of Lithuania at roughly 1–3 km altitude; coastal photographer Čepulio fotoklajonės, who filmed the object, estimated a ground speed of approximately 30 km/h. The contraption appears to have malfunctioned: by design such paired envelopes are meant to descend and land over Lithuanian territory; this one instead continued drifting toward the coast. AirVeto's reconstruction of the ICON 800 hPa wind field at 05:00 UTC on 31 January 2026 shows easterly flow (grid centre 100°, range 71°–117°) at 37–58 km/h across Lithuania — the east-to-west direction is consistent with the observed crossing, though the modeled wind speed is notably faster than the estimated ground speed (see wind section below).
Footage of the object over the coast was captured by local photographer Čepulio fotoklajonės on the morning of 31 January.

What AirVeto's wind layer showed across the transit corridor
AirVeto’s ICON 800 hPa wind field at 05:00 UTC on 31 January 2026 showed sustained east-to-west flow at 37–58 km/h (mean 50 km/h) across central and western Lithuania, with the Lithuanian-Belarusian border segments orange (inside the 85° inflow threshold) throughout the preceding night. The direction — a consistent 71°–117° easterly band, centred around 100° — is the corridor that carries anything aloft from Belarus across the full east-west extent of Lithuania toward the Baltic coast.
The modeled wind speed (37–58 km/h at 800 hPa / 2,000 m) is notably faster than the photographer’s ~30 km/h ground-speed estimate. Possible explanations: the balloon operated partly in the lighter boundary layer below 800 hPa during sections of the transit, which would reduce effective ground speed; or the visual speed estimate over featureless terrain was imprecise. At 37 km/h — the slowest point in the grid — the ~400 km east-west extent of Lithuania would take roughly 11 hours, consistent with a pre-dawn launch on the Belarusian side for a 09:00 local coast arrival. At the modeled mean of 50 km/h, the transit time compresses to ~8 hours.
The east-to-west corridor holds at all three relevant altitude bands
- 500 m: boundary-layer wind was lighter and more variable — the lower boundary layer is where ground-speed estimates from visual observation are most likely to be accurate, and where a slower effective speed (~30 km/h) is physically plausible.
- 2,000 m (800 hPa): east-to-west flow at 37–58 km/h — the east-to-west direction is confirmed; the speed is faster than the estimated ground speed.
- 5,000 m: still easterly but stronger still; would have crossed the country faster than was observed.
The direction of transit is consistent across all three levels. The speed uncertainty is real: the photographer’s ~30 km/h estimate is a visual observation, not an instrument measurement, and the boundary-layer explanation is plausible. What is not in question is that AirVeto’s January easterly field placed Lithuania in a sustained east-to-west transport corridor that morning — the object’s observed path from the Belarusian side to the Baltic coast follows that corridor.
The model behind that rendered field, and the limits on where it can be trusted, is documented on the methodology page.
The same east-to-west January flow that pushed this contraption to the coast also fed that winter's Lithuanian-Belarusian border recoveries — among them the 28 January Vilnius Airport incursion and the 6 February Druskininkai seven-balloon day.
