What is known about the flight (from Flightradar24)
The aircraft was a Boeing 737-800.
https://en.m.wikipedia.org/wiki/Boeing_737_Next_Generation
The max speed of the aircraft is 844 kph. It is unlikely to reach that speed while climbing.
https://www.flightradar24.com/blog/...2-crashes-shortly-after-take-off-from-tehran/
The aircraft took off at 2:42 UTC
Contacts was lost 2:44 UTC
The altitude was never above 8,000 feet (way below cruising altitude)
It was climbing continously until hit.
The ground speed was 275 kph.
The climb speed was 2944 feet per minute = 897 meter per minute = 54 kph
Air speed was sqrt(275^2 + 54^2) = 280 kph
The Iranians fired a Tor-M1 missile.
https://en.m.wikipedia.org/wiki/Tor_missile_system
The range of the Tor-M1 is 12 km.
It flies at 850 m/s.
The max altitude for the Tor is 6,000 meter =19685 feet.
How long time does it take for the flight to climb from its max altitude during the flight to the max altitude of the Tor M1?
19685 - 8000 = 11685 feet.
11685/climb speed = 11685/2944 = ~4 minutes.
It takes 6000/850 = 7 seconds for the Tor-M1 to reach max altitude if fired straight up.
How long time before the flight reaches the max range?
12 km / 275 kph = 2,6 minutes = 2 minutes 37 seconds.
It will climb less than 8000 feet (2,6 * 2944) in that time, so it will notreach max altitude.
The distance to 12 km at 6000 meter altitude = sqrt(12^2 + 6^2) = 13416 meters.
It will take 13416 meters /850 meters per second = 16 seconds to reach the max distance.
In reality, the flight would have been detected at least a minute earlier,
From this we can draw the conclusion that the operator had several minutes before the flight would be out of range.
What if it was a cruise missile in its final flight?
https://en.m.wikipedia.org/wiki/Tomahawk_(missile)
Cruise missiles are flying 30-50 meters above the ground level.
They have a maximum speed of 890 kph.
The target was much slower.
It was at a very high altitude for a cruise missile.
It was climbing.
It was basically in the same path as any civilian airliner taking off at the airport.
The Tor-M1 can reach such a target in approximately 5 seconds, which is way before a cruise missile can turn downwards and hit a target.
The final conclusion must be that the operator was an incompetent/uneducated moron,
and that the Iranians are lying their teeths out at every opportunity on this issue.
