On November 5, 1961, the
city of Bellinzona hosted a remarkable event in philatelic history: the "Erster
amtlicher SCHWEIZER POSTRAKETENFLUG" (First Official Swiss Rocket Mail
Flight). This experiment sought to prove the viability of using rocket
technology for rapid mail delivery across the Swiss Alps. The envelope features
striking visual evidence of its journey, including the bold red text "Befördert
mit 'Z.-Rakete'" (Carried by 'Z-Rocket') and the green Italian inscription
"ESPERIMENTI DI POSTA PER RAZZO ESPRESSO".
The historic importance of this document is cemented by the distinct circular cancellations from Bellinzona, dated 5.XI.1961, which depict a rocket soaring upward. Adding to its rarity is the blue ink signature of Gerhard Zucker, the renowned German rocket pioneer behind the "Z-Rocket" series. These marks signify a time when engineers and postal authorities looked to the stars to solve earthly logistical challenges.
