Update: Here's our resident ATTACK pilot's reponse

The pict looks like a Viper about to go beak to beak with an F-15. Both guys would have shot each other about 30 minutes previous to this position...if both were armed with AAMRAMs. The Eagle would have had the range on him though (radar range, that is...which is what counts in a Fox 1 shot). At normal closure rates (180-degree aspect, i.e., nose-to-nose), both would have the energy to get the missile to target but the Eagle would probably have seen him first, driven into optimum range, shot and then gone for the notch (hard 90 left/right to dick up the opponent's fire control/radar Doppler shift calculations and befuddle his missile just enough to preclude a lock and counter launch). That said, once the AAMRAM shifts to internal guidance, I understand it's pretty hard to beat.
