Here is what I found out surfing the internet.
This one scuba dive site tells that this Phantom crashed by a complete
hydraulic failure and the pilots bailed out.
I wrote one of these site-webmasters to ask for some information :-)
The answer I got was if I knew F4PHIXER (...wel..., his real name),
because he asked the same question the day before :-)
In my archive I found this one candidate : the 155870. This is the
only Navy Phantom I found untill now with the note: "Overboard near
the Phillippines".
By the way, I also wrote the USN/Marines Historical Dept. with this
question.
You will hear from me again :-)
Take care,
Spooky
