and finally to a container for storage and disposal. Until it closed in early 2011, a McDonald's in Edina, Minnesota claimed to be the "World's Only Pneumatic Air Drive-Thru," sending food from their strip-mall location to a drive-through in the middle of a parking lot. Technology editor Quentin Hardy noted renewed interest in transmission of data by pneumatic tube accompanied discussions of digital network security, and he cited research into London's forgotten pneumatic network. Related applications include fish cannons which use mechanisms very similar to pneumatic tube systems. Applications In postal service Pneumatic post or pneumatic mail is a system to deliver letters through pressurized air tubes. It was invented by the Scottish engineer William Murdoch in the 19th century and was later developed by the London Pneumatic Despatch Company. Pneumatic post systems were used in several large cities starting in the second half of the 19th century (including an 1866 London system powerful and large enough to transport humans during trial runs – though not intended for that purpose), but later were largely abandoned. A major network of tubes in Paris (the Paris pneumatic post) was in use until 1984, when it was abandoned in favor of computers and fax machines. The Prague pneumatic post commenced for the public in 1889 in Prague, now in the Czech Republic, and the network extended approximately . Pneumatic post stations usually connect post offices, stock exchanges, banks and ministries. Italy was the only country to issue postage stamps (between 1913 and 1966) specifically for pneumatic post. Austria, France, and Germany issued postal stationery for pneumatic use. Typical applications are in banks, hospitals and supermarkets. Many large retailers used pneumatic tubes to transport cheques or other documents from cashiers to the accounting office.
