Yes he is!
The key to low airspeed is power. Get some power on. Now. The engines the triple seven uses, the one that crashed, were high bypass turbofans made by Pratt and Whitney (others use GE's and Rolls Royce). They have an enormous fan on the front of them that is driven by a dedicated power turbine(s). From what I understand, the engines were at idle thrust. Turbine engines by nature are slow to accelerate from idle, not like a recip. Those big motors spool up even slower with all that fan mass to get spinning. The practice is to "stand the throttles up" - move them halfway up the quadrant and wait for the engines to catch up - then advance the rest of the way. That can take several seconds. By the time the cockpit crew recognized the low airspeed condition, as well as the fact that they were way below the glideslope, they had no time left for the engines to give them go around power. Sink rate got them, too. It was a classic accident.
