General-purpose bomb

A general-purpose bomb is an air-dropped bomb intended as a compromise between blast damage, penetration, and fragmentation in explosive effect.

Characteristics

General-purpose (GP) bombs use a thick-walled metal casing with explosive filler (typically TNT, Composition B, or Tritonal in NATO or United States service) composing about 30% to 40% of the bomb's total weight. The British term for a bomb of this type is "medium case" or "medium capacity" (MC). The GP bomb is a common weapon of fighter bomber and attack aircraft because it is useful for a variety of tactical applications and relatively cheap.

General-purpose bombs are often identified by their weight (e.g., 500 lb, 227 kg). In many cases this is strictly a nominal weight, or caliber, and the actual weight of each individual weapon may vary depending on its retardation, fusing, carriage, and guidance systems. For example, the actual weight of a U.S. M117 bomb, nominally 750 lb (340 kg), is typically around 820 lb (372 kg).

Mark (dinghy)

The Mark is a single-hander class of small sailing dinghy. The design probably first appeared in the 1960s, at about the same time as the Laser, but never took off as a popular racing class. The Mark is 12 feet (3.7 m) in length, with forward and side buoyancy compartments. A 19 feet (5.8 m) free standing rotating mast stepped far forward in the front buoyancy compartment supports a mainsail.

Gospel of Mark

The Gospel According to Mark (Greek: τὸ κατὰ Μᾶρκον εὐαγγέλιον, to kata Markon euangelion), the second book of the New Testament, is one of the four canonical gospels and the three synoptic gospels. It was traditionally thought to be an epitome (summary) of Matthew, which accounts for its place as the second gospel in the Bible, but most scholars now regard it as the earliest of the gospels. Most modern scholars reject the tradition which ascribes it to Mark the Evangelist, the companion of Peter, and regard it as the work of an unknown author working with various sources including collections of miracle stories, controversy stories, parables, and a passion narrative.

Mark tells of the ministry of Jesus from his baptism by John the Baptist to his death and burial and the discovery of the empty tomb – there is no genealogy or birth narrative, nor, in the original ending at chapter 16, any post-resurrection appearances. It portrays Jesus as a heroic man of action, an exorcist, healer and miracle worker. Jesus is also the Son of God, but he keeps his identity secret, concealing it in parables so that even the disciples fail to understand. All this is in keeping with prophecy, which foretold the fate of the messiah as Suffering Servant. The gospel ends, in its original version, with the discovery of the empty tomb, a promise to meet again in Galilee, and an unheeded instruction to spread the good news of the resurrection.
