Flight Crew Overcame Equipment Problem
Human Factors
On takeoff I was the pilot flying.  After taking off; I called for the gear up.  The Captain was distracted by other aircraft and helicopters operating in the vicinity and did not raise the gear.  This was my first flight in over 30 days and I was distracted flying the aircraft and making a rapid turn out at 400 feet to heading 020 for the departure.  I called for the flaps up and the after takeoff checklist on climb out.  The Captain raised the flaps and stowed the spoilers but failed to run the checklist or raise the gear.  The cockpit was very loud on departure.  I checked the pressurization (which was fine) and assumed that it had been so long since I'd flown that my memory of the noise was off.  As we passed 10;000 feet; the barber pole speed moved to show a limit of 280 knots.  This prompted the Captain to identify that the landing gear was down.  I slowed the plane above 10;000 feet and the Captain raised the gear.  The landing gear doors were oversped as the landing gear was raised.
