High-altitude military parachuting (or military free fall (MFF)) is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion. Two techniques are used: HALO (high altitude - low opening) and HAHO (high altitude - high opening).
In the HALO technique, the parachutist opens his parachute at a low altitude after free-falling for a period of time, while in the HAHO technique, the parachutist opens his parachute at a high altitude just a few seconds after jumping from the aircraft. Military HALO techniques date back to 1960, while in recent years, the HALO technique has been practiced by civilians as a form of skydiving.
In military operations, HALO is used for delivering equipment, supplies, or personnel, while HAHO is generally used only for personnel. In typical HALO/HAHO insertions the troops jump from altitudes between 15,000 feet (4,600 m) and 35,000 feet (11,000 m).
Halo- is a Greek prefix meaning "salt." In biology, it is often used to indicate halotolerance and is a portion of many words:
Halo is a live album, released in 2004, by Current 93. The front cover is a drawing by the same David Tibet which reproduces the cover of a Moody Blues album of 1971 Every Good Boy Deserves Favour.
Halo are a rock band from Bristol, England, who formed in 1999 and disbanded in 2004. In 2002, they released one album, and had three singles in the UK Singles Chart. They reformed in 2011 and are currently recording their second album.
The band’s journey began in 1999 when brothers Graeme and Iain Moncrieff joined forces with Jim Davey and then Stevie Yeomans. They developed a unique sound consisting of raw energy, soaring guitars, an unswerving rhythm section, epic songs and rich three-part vocal harmony.
Halo quickly gained a reputation for their electrifying live shows and soon found themselves on the radar of publishing giants Windswept Pacific, who snapped them up immediately after watching the band perform at The Astoria, London. Shortly afterwards Sony’s S2 label became favourites to sign them and the band promptly put pen to paper with Muff Winwood, head of Sony Europe, to sign a six album deal.
Halo’s first release, the ‘Still Here’ EP, was recorded in London and given away free to their rapidly expanding fan base with rave reviews. Kerrang urged readers not to ‘look this gift stallion in the mouth’ and to join Halo’s mailing list pronto.
