"A new feature developed for the 737-200 was a gravel runway kit. A
gravel deflector plate was added behind the nosewheel, remaining
outside the fuselage when the undercarriage was retracted. A small
tube projecting forward from the bottom of each nacelle directs blast
air ahead of the nacelle to break up the inward-rushing vortices that
can suck gravel from the ground and force it into the jet intakes."
