And if memory serves me correctly, not only had Air Florida sat too long in icing conditions at DCA, but company policy dictated a lower-than-full power setting for the takeoff:

If you are at full throttle, and keep the speed well above stall, I would be 
surprised if there is much difference in fuel consumption to climb to a 
given altitude between one safe rate of climb and another. Noise control 
requires maximum safe climb from some runways at some airports.

It has often seemed to me that DC9's climb at higher angles than most jets. 
The 757 is reputed to be the most overpowered commercial plane, but we don't 
get many around here.
