If the plane was cleared for take-off, this would have been coordinated with the defense forces, who would’ve been prepared for a civilian plane leaving Tehran. This was probably sent via a take-off window, so the plane being delayed on the tarmac missed the window.
Keep in mind also that the US had scrambled fighters from the UAE, and so there was a possibility of intrusion on Iranian airspace. So, a delayed plane outside of the take-off window may have looked like a radar-dodging fighter to an automated anti-aircraft system.
Even for an automatic detection system, this should be easy to detect as "non immediate threat"
> I am wagering an educated guess here that the technical difficulties on the plane were transponder related. If the defense missile systems the Iranian use were set up with auto interrogation, which is a fairly common thing, and the plane had issues with their transponder, which also happens then it is possible that the defense system cued the commercial flight as hostile or suspect and either launched a missile at the plane (not sure of Irans capabilities and limitations with their missile systems in regards to auto-fire) or an inexperienced operator with weapon release authority pressed a button to shoot a missile at what his system was telling him was a bad guy.
> Missile systems have a series of electronic breaks (think buttons that open and close relays allowing the missile firing voltage to reach the igintor) and mechanical breaks (think keys that have to be inserted and turned to the live/fire position). As the threat level increases the operators automate more of the process by closing these breaks. This makes for a faster response time to any threat the system identifies.
> So was it possible that an Iranian missile system was set with the minimum number of breaks/automated in a way a missile could have been inadvertently fired? I would say absolutely this is plausible given the attack a few hours prior with an expectation of an American response.

1) Militaries routinely lock-on to passenger airliners for practise.
Russia is rumored to cancel the missile launch far into the sequence, though sometimes they goof up and it fires.
2) Airlines knowingly route over war zones to save fuel, and usually only stop after a shootdown, like the MHA flight over the Ukraine.
You arm one person in a room and tell them not to shoot, and it's almost a guarantee they won't. Try this with 10 people and it's still extremely likely they won't. With 100 it's still a good chance nothing will happen. At 1,000 I'd get nervous. But keep concentrating this force over time and a shooting becomes a guarantee. Arm 31,000 police officers and wait a year and you'll see either 23 revolvers or 434 semiautomatics go off accidentally. These are all seasoned professionals and it still happens to them as a matter of statistical certainty.
So back to the incident - you can get lost in tracing something like this to the trigger man, and their immediate firepower locality but the larger perspective is that risk and danger is directly tied to policy decisions that created these conditions. Training, aptitude and fire discipline is all over the charts in any military force and if history tells us anything, it's not a stretch to call it an accident.

Most countries have their own IFF (Identify Friend or Foe) codes in their transponders. Civilian planes also have transponders that identify them as non-threats, but that is not fail proof (MH17, the 1988 Iranian incident, etc).
Summed up as: older technology, possibly manned by reservists on the final hours of the graveyard shift, nervously watching a radar screen for a counter attack from an enemy known to use electronic trickery resulted in a missile being launched at a misidentified target.
A U.S. Navy ship, the Vincennes shot down an Iranian airliner in 1988 by accident.
In many ways it's a more surprising accident since in those days the U.S. was not expecting an Iranian attack, but Iran has good reason to be on high alert and expect US warplanes now.
The US did eventually acknowledge the incident and pay reparations to Iran. What are the odds Iran does that to Canada now? Approximately zero. I'd be surprised if they even admit it, even while cornered. A number of Iranians here in Canada think it was the US that shot down the airliner. Pretty ridiculous, but if westernized Iranians living in the free world can think that, imagine what people in Iran would be willing to believe when lied to by their government.
Not now but this will become another bargaining chip and one day they may agree to pay compensation in the context of wider negotiations.
Libya agreed to pay compensations for Lockerbie 20 years later as part of wider negotiations and it is unclear whether they were involved at all...
In the Vincennes incident the AEGIS tracking software at the time reused tracking IDs for targets, and re-assigned a tracking ID from the airliner to a fighter jet 110 miles away, leading to mistaken information being relayed about the flight's activities.
This goes to show until and unless we know what information the missile system operators had, and what orders they were under, we can't really say what happened and why.

Friendly aircraft have transponders to identify them. And even without a transponder, certainly a large, slow airliner looks very different on radar than a small, fast fighter or missile.
Seems like the system would require some kind of override to fire at a friendly target.
>US media reported it had been mistakenly shot down by Iran.
I don't think this was a big missile system like the Patriot or anything. Airlines have checklists and back-n-forth with air traffic control to set their transponder and any air traffic control worth anything would be keeping track of any heavy aircraft leaving their airports which there are reports that no call of trouble was mentioned by the airliner so that means they've already reviewed the ATC tapes.
It could have been an abnormally nervous missile platoon in possession of stingers (or similar) told to be on the alert for air to ground attacks and maybe something spooked them or they were targeting the airliner like others have mentioned and someone pulled the trigger unintentionally.
It's possible that they were on high alert for fear of an American retaliatory air strike and misidentified the plane.
It seems reckless to have kept the airspace open and civilian planes flying in those circumstances, though, because, well...
Not commenting on the situation but couldn't airlines avoid tumultuous airspaces in their flight paths?
What I'm saying is that if the Iranian authorities were on such high alert for an air strike on Tehran it might have been wise to close the airspace to civilian flights instead of letting them continue to fly right in the path of ground-to-air missile batteries...
It has a mode which, when enabled, says "if you show up on my radar and do not have a friendly beacon on you, you are going to get a kilo of tungsten through your center of mass and we're not going to bother asking questions of any human first."
The use case is to prevent another Cole incident, but configuring a weapons system in such an autonomous mode means that you're in a mode where unintended deaths are acceptable, and that makes me very, very concerned.
I guess we'll all find out the official version of the story in the days to come.
Note that surface-to-air missiles are likely to target heat sources, and it seems like the engine of the airliner, a significant source of heat, may be where it was struck.
