As Ukraine stops flights, here's how European airspace looks with huge hole

Hundreds of flights had to be diverted after Ukraine closed its airspace following the escalation of the Russia-Ukraine tension on Thursday morning. The Air India flight which had to come back took off minutes after the airspace closure notice was sent to all operators and pilots.

With Ukraine closing its airspace off following Russia's full-blown attack on Thursday, several hundreds of flights had to be cancelled and diverted creating a huge hold in the east European airspace. According to reports, the airspace closure led to a 1,000-mile hole in east European airspace, as seen on flight tracker Flight Radar.

European airspace now has a huge hole with no flights flying over Ukraine. 

The flights were diverted around Ukraine after the closure. Some flights had to do a u-turn to Romania, some flights were placed in a brief holding pattern. A formal notice was sent to pilots and operators warning of the "potential hazard for civil aviation."
