Helios Airways Flight 522 was a scheduled Helios Airways passenger flight that crashed into a mountain on 14 August 2005 at 12:04 pm EEST, north of Marathon and Varnavas, Greece, while flying from Larnaca, Cyprus, to Athens, Greece. A lack of oxygen incapacitated the crew, leading to the aircraft's eventual crash after running out of fuel. Rescue teams located the wreckage near the community of Grammatiko, 40 km (25 mi) from Athens. All 115 passengers and six crew on board the aircraft were killed.
With 121 fatalities, this was the deadliest aviation accident in Greek history. Flight 522's loss marked the 69th crash of a Boeing 737 since it was brought into service in 1968. The crash is the fourth-deadliest involving a 737-300.
The aircraft involved in this incident was first flown on 29 December 1997 and had been operated by DBA in 1998 until it was leased by Helios Airways on 16 April 2004 and nicknamed Olympia, with registration 5B-DBY. Aside from the downed aircraft, the Helios fleet consisted of two leased Boeing 737-800s and an Airbus A319-111 delivered on 14 May 2005. The aircraft had arrived in Larnaca from London Heathrow at 01:25 that morning. The flight was scheduled to leave Larnaca, Cyprus, at 09:00 am local time, and fly to Prague via Athens. The scheduled arrival time in Athens was 10:45 am. Hans-Jürgen Merten, a 58-year-old German contract pilot hired by Helios for the holiday flights, was the captain. He had been flying for 35 years (including for Interflug before 1990) and had accrued 16,900 flight hours. Pampos Charalambous, 51, a Cypriot who flew for Helios, served as the first officer and had worked exclusively for Helios for the last five years. Charalambous had accrued 7,549 flight hours throughout his career. Louisa Vouteri, a 32-year-old Greek national living in Cyprus, replaced a sick colleague as the chief purser.
Tree is an album by Irish folk singer Johnny Duhan.
A tree is a perennial woody plant.
Tree or trees may also refer to:
In computer science, a tree is a widely used abstract data type (ADT)--or data structure implementing this ADT--that simulates a hierarchical tree structure, with a root value and subtrees of children with a parent node, represented as a set of linked nodes.
A tree data structure can be defined recursively (locally) as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of references to nodes (the "children"), with the constraints that no reference is duplicated, and none points to the root.
Alternatively, a tree can be defined abstractly as a whole (globally) as an ordered tree, with a value assigned to each node. Both these perspectives are useful: while a tree can be analyzed mathematically as a whole, when actually represented as a data structure it is usually represented and worked with separately by node (rather than as a list of nodes and an adjacency list of edges between nodes, as one may represent a digraph, for instance). For example, looking at a tree as a whole, one can talk about "the parent node" of a given node, but in general as a data structure a given node only contains the list of its children, but does not contain a reference to its parent (if any).

South is the name for a ward in the southern part of Luton, England. The ward includes New Town, Park Town, Chapel Langley and most of Luton town centre. Junction 10 of the M1 is just outside the ward. Both Luton Airport Parkway and Luton railway station are located within the ward. London Luton Airport is close by.
The local area is a mixture of residential and commercial, yet the area itself has traditionally been associated with the working class population. However, a series of developments towards Stockwood Park and Golf Centre, on the edge of Luton, have helped to bring in new residents, lifting the area. There is a local business park, Capability Green, and nearby, Gypsy Lane Retail Park on the A1081 and towards Castle Street heading up towards the town centre, new businesses have been setting up, boosting the area further. There are a series of local pubs in the area with a diverse culture behind every one of them, making the area one of the most diverse in Luton.
South Crater is an impact crater in the Mare Australe quadrangle of Mars, located at 77.1°S latitude and 338.0°W longitude. It is 107.1 km in diameter and was named after Sir James South, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).
Very close to the crater there is what has been named "Swiss cheese" features. Swiss cheese features (SCFs) are pits so named because they look like the holes in Swiss cheese. They were first seen in 2000 using Mars Orbiter Camera imagery. They are usually a few hundred meters across and 8 metres deep, with a flat base and steep sides. They tend to have similar bean-like shapes with a cusp pointing towards the south pole. The angle of the sun probably contributes to their roundness. Near the Martian summer solstice, the sun can remain continuously just above the horizon; as a result the walls of a round depression will receive more intense sunlight, and sublimate much more rapidly than the floor. The walls sublimate and recede, while the floor remains the same. As the seasonal frost disappears, the pit walls appear to darken considerably relative to the surrounding terrain. The SCFs have been observed to grow in size, year by year, at an average rate of 1 to 3 meters, suggesting that they are formed in a thin layer (8m) of carbon dioxide ice lying on top of water ice.
Wings (ウィングス, Uingusu) is a shōjo manga magazine published by Shinshokan.
