We used to do quite a few 3 eng ferries back in the early 90's. The 188 was so overpowered it didn't pose much of a problem. You would line up on the r/w and advance the two symmetrical engines and as you began to roll you would advance the 3rd to have it at full power at about 100kts. All this time however you are hoping that a second eng doesn't fail because that really could have ruined your day.
As for as the prop not rotating the engineers would lock it so it didn't go round
Also, there were two Atlantic Electras on the DHL ramp in Brussels on Friday night. Its great to see them still flying around.
