Factual narrative
THE PLT HAD BEEN WAITING IN LINE FOR TAKEOFF ON RUNWAY 16 FOR OVER AN HOUR, DUE TO TRAFFIC DEPARTING AIR RACES. WHEN CLEARED TO DEPART, WINDS WERE 300 DEG AT 15 KTS, GUSTING TO 22 KTS. PLT ELECTED TO ATTEMPT TAKEOFF, BECAME MOMENTARILY AIRBORNE WITH STALL WARNING HORN SOUNDING. WHEN PLT LOWERED NOSE OF ACFT TO COMBAT STALL, ACFT LNDG GEAR STRUCK A DIRT MOUND PARALLEL TO RIGHT OF RUNWAY. DENS ALT CALCULATED AT 5000 FT.
