and after having checked two maps for reference you can say that the jet crossed approximateley 3.5 to 4km of turkish airspace. In order to cross this territory, the Su24 had to fly 3500/17*3.6 = 741km/h (4000/17*3.6 = 847 km/h if you take the 4km or 526.3 MPH for the more US based persons here). The highest speed possible for a Suchoi Su24 is Mach 2,18.
Not calculated into this is a possible climb that may have been performed by the pilots, requiring a faster speed in order to cross this 3.5 to 4km in 17 seconds.
I honestly don't know from which airbase the aircraft started, how long it took the jet to aquire it's needed heigth and how long the whole mission had taken until that time. It still is common practice to warn military aircrafts at least 5-6min before they reach the border, giving them time to turn around. There still needs to be a quite large timeframe in order to have enough time to get the two F16s in the air, what normally is initiated when the first warning is spoken. Give me some time to calculate the time it took the jet to reach the border.
I will still need some time to figure a Su24's stall speed out, but you are able to fly easily with 741 - 847 km/h (A normal, much heavier plane like the Boeing 747-300 flies at 910km/h travelspeed with 377.000 kg! A Su24 only has 36.000 kg!!!). It also is more comfortable for the pilot to stay under Mach 1,0 as the body is not pressed into the seat then. And yes, aircrafts usually do not fly on highest speed when fighting groundtargets as you don't have enough time to use your weapons properly against groundtargets when on fullspeed and also are heavily pressed into your seat when on fullspeed.
PS: The one not providing any necessary proof for his assertion is you; please refrain from posting before having calculated anything, thanks.
1. You didn't provided any more "proof" than I did. And I must stress that the media provided all the necessary evidences, including those that you dismissed.
2. Amongst those evidences, you dismissed half of Turkey's letter to NATO, which says that the plane stayed for 17 seconds in their airspace but also admits that it represented "1.15 miles in lenght", which is 1.6 kilometers and not 3-4 as you said. The result is a speed of 338.8212km/h, which is less than HALF of your own result, and this is a complete nonsense.
3. According to the radar picture provided by Turkey (but probably made on Paint), the plane which was shot turned in the direction of Turkish territory a maximum of 1.5 minutes before it was downed. Now if they had warned the pilots 5 minutes before, it means that they warned them as they were flying SOUTH/SOUTH-EAST.
4. Finally, the location of the Russian airbase that you couldn't provide is well-known. It's the Khmeimim air base at Latakia. It's located less than 50 kilometers South-West from this part of the Turkish border. Which means
that all Russian planes going North would need to get warned by Turkey as they would need less than 5 minutes to go there (5 minutes at 600km/h). Moreover, ALL RUSSIAN PLANES IN THIS AREA, turning North even for a moment, would have to get warned.
This is, once again, the evidence that Turkey is completely lying and that they never warned the pilots.
