This means that the limited handwriting contained within the message "...Flight 555 SF. 700 P.M. P.M." was redacted from the image we are accustomed to. It appears that the pasted FLT 555 was referring to "Flight 555" after all. Very likely from San Francisco at 7:00PM, according to the sender. Howard Davis of the Zodiac/Manson website, reported that Drew Peterson relayed information about a reporter who found a United Flight 555 that flew from San Francisco to San Diego every Wednesday at 7:30pm, tying in with the "Birds Fly South" pasted text on the Day-By-Day Forecast for Cancer communication. This almost lines up with the notation of Flight 555 SF. 700 PM (using a viniculum under 00), which was written on the horoscope page (Q40). The mailing date of the Day-By-Day Forecast for Cancer communication and the abduction of Leona Roberts were both on a Wednesday. Howard Davis has toyed with the idea that the Zodiac Killer was giving hints he was more than capable of traveling to San Diego, where on February 4th 1964 at Ocean Beach, Johnny & Joyce Swindle were murdered by a sniper alongside the seafront. Bolinas Lagoon (where Leona Roberts body was found) and San Diego Bay are also both key sites in the Pacific Flyway for migratory birds.
