If I had to choose the least favoured job for the FO,it would have to be the internal tail inspection. For those dear readers who are not familiar with DC9 ops; on the first flight of the day,the FO had to enter the tail via the drawbridge, that was the pull down ceiling above the rear ventral stairs. Inside the tail it was dark(no windows),hot(outside the airconditioned area) & NOISY( shared space with the APU). We had to check emergency slide pressure,enough tape left on the crash recorders & any suspicious devices which may have been hidden aboard. We were a nuisance to catering who couldn't come up the back stairs,cleaners who couldn't leave by the backstairs & flight attendants because we were holding everything up.
