Question- have read in certain fictions that a High altitude parachutist might have scuba equipment, allowing them to land in the water, cut off parachute equipment, and thus continue insertaion submerged. Is the even possible? Wouldn't the Double change in pressure (low pressure from high altitude, to increased preassure submerged) present EXTRA health risks TOO risky

[edit] To Do

  1. the method is atributted to USAF Col. Joe Kittinger [1] but perfected by U.S. special forces
  2. add background information in which Kittinger's experiment and USAF's needs are explained
  3. HALO is really a form of skydiving, as civilians practice the free-fall method as a hobby [2] (information regarding the military should remain on the article anyway)
  4. [3] StratoQuest: a record-setting high altitude skydive from 130,000 feet, dedicated to scientific research, education, and space exploration. See also: [4]
  5. Add WHY somebody would do a HALO or HAHO techniques, and what are the advantages and disadvantages of them.

[edit] Time correction

In a typical HALO exercise, the parachuter will jump from the aircraft, free-fall for a few seconds and open his parachute at a low altitude. Doesn't it take a couple of minutes to drop from 20,000ft to HALO chute opening altitude? DJ Clayworth 04:03, 23 Feb 2004 (UTC)

I wouldn't say couple of minutes in HALO.. but neither a few seconds. I was trying to express that it can go from 30 seconds to 1 minute+ or something like that. Feel free to change it so that it expresses it better. :)
I jumped at 15,000 feet once and opened at 5,000 and the freefall was just over a minute. I think if you jumped at 27,000 feet and opened at a couple thousand, it would easily be two minutes. --Jkonrath 23:02, 31 January 2006 (UTC)

Freefall for military purposes is usually in the 60-65 second range for HALO. Jumps can be as high as the mission dictates if oxygen is used, and the normal opening altitude is around 4,000 feet. HAHO jumps vary greatly based on the mission because of the navigational concerns. There is very little freefall, but the time in the chute until landing can routinely exceed 20 minutes. Great book on the subject is Code Name: Copperhead, Sgt. Maj. Joe R. Garner's autobio with Avrum M. Fine. The birth of MFF and the formation of the Golden Knights are also discussed in it.

As with all skydiving, participants run the risk of parachute failure, resulting in instantaneous death upon contact with the ground. That's somewhat... obvious. Although I have heard of some cases where people lived falls from planes, but perhaps at a lower altitude that a HA type jump. --68.13.59.58 04:45, 22 January 2006 (UTC)

It doesn't matter what altitude you fall from really, you'll still hit terminal velocity before you hit the ground. Those that have survived were VERY VERY lucky.

[edit] Recruiting Attempt

In response to the request for expert assistance I emailed the POC for this site: http://www.batnet.com/mfwright/miljump.html to see if he would be interested in assisting with this article. Unfortunately he checked the site after it had been vandalized (12:10, 1 June 2006). Because of the persistant vandalism, I don't believe he's interested in editing the site, but there may be some information from his site that may be of use in developing the article, if corroborated. 71.113.73.83 08:52, 4 June 2006 (UTC)
