Moreover you first would have to decellerate from ~470kts at 2:10:00 to less than 60kts (final speed would have to be even slower due to the higher speed at the beginning) in 4 mins without traveling further than 4nm.
henra theoretical: if the bird is without any control but starts with an extrem climb mayby 60 deg, this (~balistic) path will reach a maximal high of ~12700m (full change the kinetic horizontal energie into potencial energie), while reducing the speed to very low untill it will deap stall and if it then fall with a stable AOA of 50-60 deg. back to 10500m and afterwards down to zero.....
this path could need ~100 sec longer than yours and can end within a range of 8000m
