Not sure how true this is.....
As per this story the rumour is it caught fire in a Hangar after a helicopter gun fight broke out over the airport in which it was in, another story is that it crash landed with 16 Crew on board....
Airlive.net are confirming AN225 is on the ground in Hostomel Kyiv but apparently FR24 are reporting it flew to Penang in Malaysia this morning. FR24 is currently using a waiting room with a wait time of 32 minutes.
