"England joined the Zeppelin Air Mail Service to South America in March 1932. Zeppelin mail from England, Ireland and other British Territories (including Gibraltar), was collected in London and forwarded to Berlin, from where it was transported by special connecting plane to Friedrichshafen, where it was loaded onboard the Graf Zeppelin for its journey to Recife, Pernambuco, Brazil, South America. This route is confirmed by the manuscript endorsements on Zeppelin mail “Pour dirigible Graf Zeppelin via London/Overland” or “via Friedrichshafen (Allemagne)”.
Gibraltar mail to Great Britain was sent in ‘Closed Mail’ (sealed) bags, which were not opened until they reached London. They were handled as ‘Intact Bags,’ handed over to the Spanish Post Office at the border town of La Linea. From here they travelled overland to the railhead at Algeciras, thence onto Madrid and Paris. Surface mail from Paris was transported to London via the Channel port of Calais (usually), but also via Bologne. There is no way of knowing which route was used on any particular occasion. In 1935 there was no direct airmail service between Gibraltar and London.
Between April and June 1935 Zeppelin flights occurred every two weeks, alternating the weekly mail service to South America with Deutsche Lufthansa (DLH) Catapult mail services. Zeppelin Flights were directly between Friedrichshafen and Recife, Pernambuco, Brazil via Larache, Spanish Morocco, where connection was made with DLH flights carrying late airmail from Berlin and Stuttgart. From July 1st 1935 DLH became the exclusive German carrier of letter mail on the South Atlantic route as it had proved both faster and more reliable than the Zeppelin service, while at the same time, DLH and Air France began cooperative twice-weekly airmail service on the South Atlantic route (DLH from Stuttgart on Thursday, Air France from Paris on Sunday). Zeppelin continued to provide only a non-letter mail services (Trans-Atlantic flights 8 to 14) except on those occasions where refitting of the catapult supply ships restricted trans-Atlantic flights. The non-letter airmail included printed matter, business and printed papers, samples, packets and parcels.
In late October 1935 the DLH catapult supply ships were withdrawn for servicing. The Graf Zeppelin was again used for regular South trans-Atlantic mail delivery. For the Germany-South America flights 15 and 16 the Graf Zeppelin also picked up mail that was delivered via DLH to Larache. Between flights 15 and 16 there was one further DLH flight to South America (Departure from Stuttgart 31st October, arrival 2nd November). For the period 15th – 30th November the LZ-127 made three return flights from Recife to Bathurst, Gambia delivering northbound mail to the DLH and picking up southbound mail from DLH. These flights, known as “pendelfahrten” (pendulum) or shuttle flights, involved picking up the mail in Bathurst in special wire baskets dropped from the airship." [E.Chambers, N.Donen].
