References
- Various primary sources were examined, including:
- Drawing Office Copy (Andrews Notebook): Mentions two electric steam whistles on the forward funnels.
- The Shipbuilder: States that one set of whistles was fitted to the two foremost funnels.
- Engineering: Notes that the two whistles were controlled by the Willett-Bruce system.
- Post-disaster testimony: Indicates the whistles were not used the night of the disaster.
- Olympic Auction Catalog (1935): Describes sirens fitted to all four funnels.
- C.C. Pounder (1922): Mentions that cast-iron whistles and dummy pipes were often fitted to dummy funnels, suggesting non-functional whistles on the aft funnels.
Wreck Evidence
- Differences in the construction and materials of the whistles were noted:
- Forward Whistles: Made of cast metal, which fractures under stress.
- Aft Whistles: Made of wrought metal, which bends under stress, likely a less expensive metal like Muntz metal.
Functional or Non-Functional?
- The evidence suggests that while the aft whistles were different in construction, there is no direct reference confirming they were non-functional.
- C.C. Pounder’s reference to non-functional whistles on dummy funnels is the most persuasive evidence supporting the claim.
Conclusion
- The article concludes that the aft two whistles on Titanic were more likely non-functional based on the available evidence and primary references, particularly the statement by C.C. Pounder.
