Thain told the station engineer, Bill Black, about the problem with the boost surging in the port engine, and Black suggested that since opening the throttle more slowly had not worked, the only option was to hold the plane overnight for retuning. Thain was anxious to stay on schedule and suggested opening the throttle even more slowly would suffice. This would mean that the plane would not achieve take-off velocity until further down the runway, but with the runway almost long, he believed this would not be a problem. The passengers were called back to the plane 15 minutes after leaving it.
