Luftwaffe Air Sea Rescue Aids
Apparently Luftwaffe aircrew had canisters of dye to release if the ditched, which turned the sea a florescent yellow, so as to allow them to be seen more easily from the air. What was this dye or substance they used? Was there an Allied Aircrew equivalent?

Re: Luftwaffe Air Sea Rescue Aids
It was a yellow/green Fluorescein Dye. Fluorescein is a florescent organic dye. In the rescue markers it is in the form of fluorescein sodium,

C20 H10 Na2 O5 (a water soluble salt of fluorescein).

or https://en.wikipedia.org/wiki/Seenotdienst


The allies used similar markers.
