Question: Rather than leaving Stackhouse behind in the area where the Serbians could find him, wouldn't it have made more sense for Burnette to pick Stackhouse up, and help him get up the hill?
Answer: Stackhouse is badly hurt. Burnett would have known better than to move him. Plus, with the way he speaks to Stackhouse it's clear they weren't expecting company so quickly.
So what if Stackhouse has an injured leg, why not just help in him walk? Soldiers in combat help their follow soldiers walk when they have injured legs.
Question: The SAM missiles continuously chases the fighter jet for a few minutes. In reality, don't SAM missiles only contain enough fuel to fly for about 5 to 10 seconds?
Answer: Surface-to-air missiles come in 3 ranges (long range, medium, and short). Long range missile have a range of 100-150 km (there are some very long ranged missiles that can go up to 400 km). Short range missiles go about 3 km. SAM's are faster than Air-to-Air missiles and can travel around Mach 3 and up to Mach 8, with some that can go faster (so about 1 - 2.7 km/s) I don't know what kind of SAM was used, but long range SAM's are fired from a fixed or semi-movable position and medium ranged SAM's can be fired from vehicle mounted systems.
A behind enemy lines goof from IMDb, says that no missile is capable of chasing the F/A-18 as it is portrayed in the movie. A missiles rocket motor only holds enough fuel for one pass at a target. I don't know if you agree with it or not.
I would disagree with the statement that it wouldn't have enough fuel. However, even after a missile runs out of fuel it can still glide to its target at supersonic speeds for a time. I do think the portrayal of the chase scene is overly dramatic in Hollywood fashion though, particularly for the first SAM fired.
According to the trivia of the film the missile used was a 9m37m missile.
In that case the scene is completely Hollywood and unrealistic. The 9m37m is a short range missile, even though it's vehicle mounted, and has a max range of 5 km and doesn't even reach Mach 2. When the 2nd missile is fired we hear one of the pilots say "3 miles and closing", meaning the SAM shouldn't have been able to catch up to them or chase them down. The film makers probably wanted something cool looking without considering (or caring) what they had or may not have access to a midrange SAM system and pretended it was one.
But don't long range missiles lack the ability to turn fast enough to follow and chase a jet due to the weight of the amount of fuel they carry?
Answer: Because in escape and evasion, as opposed to combat, you are taught to get away from where you have landed as fast as possible. And Stackhouse probably believed his pilot would be treated humanely under the Geneva Convention.
