More than 1 hours has past and status is still on "scheduled

Hi guys, I’m tracking a flight overseas and it seems like the status is stuck on “scheduled”. The plane was suppose to take off 1 hour and 30 minute ago and I don’t link there is a delay.

Here is the link … /OIIE/OTBD

That flight does not operate in our primary service areas, so accuracy of the data is limited.
