Yes, I was assuming that it was a mistake by Olliver (or even Scott who may have been some distance from the telegraph). I doubt there were two ahead orders.
The timing really depends on how long the lights were out for, and thus how long we can allow between Hendrickson leaving and Olliver arriving in the engine room. It is possible it was after Olliver talked to the carpenter, but that would depend on how long it takes to get to the engine room. Here is some testimony:
Senator BURTON.
Did you hear him report anything to the captain?
Mr. OLLIVER.
No, sir; I did not wait for an answer. As soon as I got on the bridge, I had another message.
Senator BURTON.
What was the other message?
Mr. OLLIVER.
A message to take to the chief engineer.
So he could not have stood on the bridge for more than a few moments. Would it take him 2 mins (and this is the lower estimate for how long the engines ran ahead for) to get from there to the engine room?
As for the time period the engines ran ahead for, Dillon states the engines ran ahead for 2 mins, Scott claims 10 mins. Scott said there was 10-15 mins between stop and ahead (which fits with my timeline, as I think 10mins for Barrett is far to late: more likely 5mins). However, it is hard to know who is better at judging times. Dillon also has the engines running in reverse, which seems odd as most people (except
Boxhall) state the engines just stopped (although the point was not really pressed, so it is possible these people just did not mention it).
Would running the engines ahead help to get rid of excess steam (as an alternative idea to those presented already)?
Oh, and how did the carpenter take a draft on E deck?
