How do I know it was an IOE?
1) Sat in 1c (last seat in the house). FO was being instructed on how to use the door, adjust his seat, use the PA and how to fill out the paper work.
2) every PA was repeated by the captain as the FO did not know how to use the PA- He was completely unintelligable.
3) After 16000 hours in part 121 and years in corporate you know how things work!.
I came up through the ranks, CFI, corporate, regional, 121, furloughed, 121, corporate. A 1st class operation this was not!
