In 1925, the F-VII was replaced by the Fokker F-VIIa, the first passenger aircraft with an air-cooled radial engine and a metal propeller.
This plane was somewhat larger than his predecessor and could carry eight passengers. A number of technical improvements had also been made, one of which undoubtedly received a warm welcome from passengers: the cabins were now heated in winter.
In the early years, flight services were suspended on 31 October, because the unpredictable weather conditions made it difficult to fly to schedule in winter and the cabins were still unheated. With the arrival of more comfortable planes, which included state-of-the-art technical improvements such as 'ireless telephones', KLM took the icy plunge and decided to start a winter service.
Passengers, however, were far from convinced, judging by the management's following remark: 'The view that travelling by plane in winter is uncomfortable, is also playing an increasingly important role.
It is for this reason that KLM has repeatedly emphasised the fact that the cabins are kept well heated during the winter'.
|A lot of the aviation terminology stemmed from maritime jargon: the Dutch word 'kajuiten' (cabins) was used to refer to the cockpits.
The poster left was clearly intended to convince the public that travelling in winter had become comfortable: the passengers have taken off their winter coats and are looking over a wintry landscape (the ones we don't have anymore in Holland)
