Up Helly Aa from Upholiday, the lowland Scots word for Twelfth Day, and was brought by them to the Shetland Islands in the 19th century. There is a main guizer who is dubbed the "Jarl". There is a committee which a person must be part of for 15 years before one can be a jarl, and only one person is elected to this committee each year. The procession culminates in the torches being thrown into a replica Viking longship or galley. The event happens all over Shetland and is currently celebrated at ten locations – Scalloway, Lerwick, Nesting and Girlsta, Uyeasound, Northmavine, Bressay,
Shetland Bonhoga Gallery at Weisdale Mill and Jarlshof. Transport between islands is primarily by ferry, and Shetland Islands Council operates various inter-island services. Shetland is also served by a domestic connection from Lerwick to Aberdeen on mainland Scotland. This service, which takes about 12 hours, is operated by NorthLink Ferries. Some services also call at Kirkwall, Orkney, which increases the journey time between Aberdeen and Lerwick by 2 hours. There are plans for road tunnels to some of the islands, especially Bressay and Whalsay; however, it is hard to convince the mainland government to finance them. Sumburgh Airport, the main airport
