Force Z had eight Supermarine Walrus seaplanes. None were used to reconnoiter ahead of PoW and Repulse to look for IJN landing ships. Instead, Phillips opted to rely on the Mk I Eyeball to look for the Japanese ships, putting his own ships into deadly harm's way.

WI Phillips had kept his ships well back and instead used his aircraft to search up the coast for IJN landing ships?



The downside is any IJN ships found will be well out of range of PoW and Repulse's intervention. However hindsight tells us there were no IJN ships, so the upside is PoW and Repulse are likely beyond the range of IJN/A strike aircraft.
