2023 Moldova And Romania High-altitude Objects
On 14 February 2023, an "aerial object that looked like a weather balloon" was spotted flying at approximately in southeastern Romania. Two MiG 21 Lancer fighter jets were scrambled to the area, but returned to base after not receiving visual or radar confirmation of the alleged object. The same day, the neighboring nation of Moldova closed its airspace to investigate a "balloon-like object" allegedly spotted in the north of the country, near its border with Ukraine. After it was declared that there was no danger to civilians, the airspace was reopened an hour and twenty-two minutes later. Incidents At around 12.30 p.m. on 14 February, the air surveillance systems of the Romanian Air Force detected a small-sized aerial target similar to a weather balloon flying at an altitude of 11,000 meters over the South-East of Romania. Two MiG-21 LanceRs under NATO Air Policing command were scrambled from the 86th Air Base. The two fighters could not identify the target, neither visually ...

Weather Balloon
A weather balloon, also known as sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as ''transosondes''. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and the height of cloud layers. For such balloons, a theodolite or total station is used to track the balloon's azimuth and elevation, which are then converted to estimated wind speed and direction and/or cloud height, as applicable. Weather balloons are launched around the world for observations used to diagnose current conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romania
Romania ( ; ro, România ) is a country located at the crossroads of Central Europe, Central, Eastern Europe, Eastern, and Southeast Europe, Southeastern Europe.

MiG 21 Lancer
The Mikoyan-Gurevich MiG-21 (russian: Микоян и Гуревич МиГ-21; NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. Its nicknames include: "balalaika", because its planform resembles the stringed musical instrument of the same name; "''Ołówek''", Polish for "pencil", due to the shape of its fuselage, and "''Én Bạc''", meaning "silver swallow", in Vietnamese. Approximately 60 countries across four continents have flown the MiG-21, and it still serves many nations six decades after its maiden flight. It set aviation records, becoming the most-produced supersonic jet aircraft in aviation history, the most-produced combat aircraft since the Korean War and, previously, the longest production run of any combat aircraft (now exceeded by both the McDonnell Douglas F-15 Eagle and General Dynamics F-16 Fighting Falcon).
