Flying low or high is a matter of endless discussions-both is right and wrong.
Having flown everywhere from Afghanistan to Sudan, from Somalia to Iraq, you have to fly at the right altitude in this right moment.
Flying low-you are an easy target for small arms fire (a bigger hazard than Gnd-2-Air Missiles)....
Flying high-you are in range for any Sam-7, Strela or whatever...
The most important thing is to NOT forget where you are flying......some pilots get complacent in these austere environments....and start flying like they are at home...
