Hi,
would it be possible to make an air-to-air missile (or a surface-to-air one) climb to a set altitude (say, 20km) before beginning the glide/powered flight to the target craft? I find that the current behavior doesn't work very well with missiles that have their engine burn out at higher distances to the enemy (50-60km) - they don't have a lot of energy remaining to chase after the craft. The missile doing an initial climb to 20km, then thrusting/gliding to the enemy craft could help interceptions by having more energy by the time of interception.
In addition, making AAM and AGM missiles respect the cruiseSpeed config parameter may help realism - currently, missiles achieve speeds higher than their IRL counterparts rather easily (especially when attempting to intercept ballistic missiles high above)
