Probably that's what happened. But it wasn't the only plane in the ait at that time. Here's a flightRadar recording of the relevant time. There are several planes flying around there. That's strange at a time when they fired missiles 2 hours before.  https://www.youtube.com/watch?v=LC-4sliKIck  Here is a replay video of Flight PS752, the Ukranian plane that crashed in Iran, you can see all planes around it flying safely, then as it takes off something happens 00:48 mark (No sound in the video)
