sometimes  yelled  his  name  when  they  jumped  out  of  airplanes.
                           Tinkerbell  is  a  fictitious  flying  character  from  the  children's  novel
                           Peter Pan). In any case, if the derrickman has to get out of the derrick
                           or mast quickly, he or she grasps a handle on the Geronimo and rides
                           it  down  on  a  special  cable,  or  line,  to  the  ground.  The  derrickman
                           controls  the  rate  of  descent  by  moving  the  handle  to  increase  or
                           decrease braking action on the line.
                                  When  the  bit  is  drilling  and  the  pipe  is  in  the  hole,  the
                           derrickman, using a built-in ladder in the derrick or mast for normal
                           descent,  climbs  down  from  the  monkeyboard  and  works  at  ground
                           level.  When  not  in  the  derrick  or  mast,  derrickman  monitor  the
                           condition  of  the  drilling  mud.  They  make  sure  it  meets  the
                           specifications for drilling a particular part of the hole.
                                  Rotary Helpers (Floorhands)
                                  Depending  on  the  size  of  the  rig,  its  equipment,  and  other
                           factors,  a  contractor  usually  hires  two  or  three  rotary  helpers,  or
                           floorhands, for each work shift. On small rigs drilling shallow wells,
                           for example, two rotary helpers on a shift can safely and efficiently
                           perform  the  required  duties.  On  large  rigs  drilling  deep  holes,  and
                           offshore, the job usually requires three rotary helpers, but not always.
                           In either case, on conventional rigs, rotary  helpers handle the  lower
                           end of the drill pipe when they are tripping it in or out of the hole.
                           They  also  use  large  wrenches  called  “tongs”  to  screw  or  unscrew
                           (make  up  or  break  out)  pipe.  Some  tongs  are  power  tongs,  which
                           replace conventional tongs. Besides handling pipe, rotary helpers also
                           maintain the drilling equipment, help repair it, and keep it clean and
                           painted.
                                  Rotary helpers get their name from the fact that much of their
                           work occurs on  the  rig  floor,  near  the  rotary  table  –  the  traditional
                           device  that  turns  the  drill  pipe  and  bit.  Originally,  they  were  also
                           called  ,,roughnecks,"  probably  because  those  who  worked  on  early
                           rigs prided themselves in being rough and tough. Later, they became
                           rotary helpers, which added a little dignity to the title. They are also
