Circa 1976-1980, this is a HI\/LO Free Fall Parachutist helmet. The helmet was officially known as; Helmet, Parachutist’s, Free Fall, Type I, Without Communication Equipment. It has a nice label on the interior denying the size as small. This helmet was used for hi-lo or lo-lo parachute drops by specially trained troops for infiltration under the radar.

Two techniques are used: HALO (high altitude – low opening, often called a HALO jump) and HAHO (high altitude – high opening).\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003eIn the HALO technique, the parachutist opens the parachute at a low altitude after free-falling for a period of time, while in the HAHO technique, the parachutist opens the parachute at a high altitude just a few seconds after jumping from the aircraft.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003eAlthough HALO techniques were first developed in the 1960s for military use, in recent years HALO parachute designs have been more widely used in non-military applications, including as a form of skydiving.\u003c\/p\u003e\n\u003cp\u003eIn military operations, HALO is also used for delivering equipment, supplies, or personnel, while HAHO is generally used exclusively for personnel. In typical HALO\/HAHO insertions the troops jump from altitudes between 15,000 and 35,000 feet (4,600 and 10,700 m). Military parachutists will often reach a terminal velocity of 126 mph (203 km\/h), allowing for a jump time under two minutes.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":40303395504197,"sku":"ONSV8958","price":295.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/products\/ONSV8958__01.jpg?v=1662742837","url":"https:\/\/www.ima-usa.com\/products\/original-u-s-cold-war-halo-hi-lo-free-fall-parachutists-helmet-size-small","provider":"International Military Antiques","version":"1.0","type":"link"}
