A novel parachute and method of manufacturing can be performed quickly and inexpensively. The parachute comprises a canopy having a plurality of gores with interior and exterior sides, and a pocket on the interior side of the gores formed either with folded or gathered or folded and gathered material from the gore. Preferably, each gore is fastened to adjacent gores at two spaced locations to form longitudinal apertures between gores. When the parachute is deployed some air initially passes through the apertures. However, instead of acting as a single unit like a traditional canopy each gore initially inflates separately in the crown region. As the gores become inflated they work together to close the apertures between the gores and trap air as a single unit.

1. A method for making a parachute canopy from a suitable gore material comprising the steps of:(i) creating a pocket in an interior side of at least one of a plurality of gores having interior and exterior sides by a step selected from the group consisting of folding, gathering and folding and gathering a piece of said gore material;(ii) connecting surfaces of said folded, gathered or folded and gathered gore material of a given gore to form said pocket, and(iii) connecting said plurality of gores together to form said parachute canopy. 2. The method recited in claim 1, wherein said gores are generally triangular shaped. 3. The method recited in claim 1, wherein said plurality of gores are connected together proximate to said pocket of each of said gores. 4. The method recited in claim 1, wherein each of said plurality of gores comprises a pocket. 5. The method recited in claim 1, wherein said surfaces of said gore material are connected by sealing. 6. The method recited in claim 1, wherein said pocket is generally cone shaped. 7. The method recited in claim 1, wherein each gore is fabricated from a single piece of said gore material. 8. The method recited in claim 1, wherein connections of adjacent gores of the canopy are spaced from one another to form apertures therebetween. 9. The method recited in claim 8, wherein said gores comprise an upper first end, and a lower second end opposite said first end, said method comprising the step of forming a skirt or tapering said lower second end of said gores to form flared ends. 10. The method recited in claim 9, wherein said canopy comprises a crown at said upper first end, and the method includes the step of joining said plurality of gores at least at points in proximity to said crown. 11. A method for making a parachute canopy comprising the steps of:folding a plurality of rectangular gores in half parallel to a pair of long sides, each of said gores having two short sides and two long sides;sealing a first short side of each of said plurality of gores to form an inflation pocket in each of said gores;connecting said plurality of gores together proximate said inflation pockets; and,connecting adjacent corners of a second short side of said plurality of gores. 12. A method for making a parachute canopy comprising the steps of:folding over an end portion of a first end of a plurality of rectangular gores, said gores comprising two short sides and two long sides, wherein said first end is one of said short sides and a second end is an opposite short side;sealing said long sides of said folded over end portion to form an inflation pocket in each of said gores;connecting said plurality of gores proximate said inflation pockets; and,connecting adjacent corners of said short sides at said second end of said plurality of gores. 13. A parachute, which comprises a canopy having a plurality of connected gores, said gores having interior and exterior sides, and a pocket comprising connected surfaces of said interior side of at least one of said gores, wherein said connected surfaces of said pocket are formed from folded, gathered or folded and gathered material of a given gore. 14. The parachute recited in claim 13, wherein said gores of the canopy are connected to each of two adjacent gores in at least two locations along sides of said gores. 15. The parachute recited in claim 14, wherein the pockets of said gores are generally triangular shaped. 16. The parachute recited in claim 14, wherein said pockets are in the form of a pouch or envelope. 17. The parachute recited in claim 13, wherein each of said gores and pockets are fabricated from a single piece of material. 18. The parachute recited in claim 13, wherein each gore of said canopy further comprises an upper first end, a lower second end opposite said first end, a pocket at said upper first end and a skirt or tapered flare at said lower second end. 19. The parachute recited in claim 18, wherein said canopy comprises a crown at said upper first end of said gores, said gores connected in proximity to said crown. 20. The parachute recited in claim 13, wherein each gore comprises a pocket which is an inflation pocket. 21. The parachute recited in claim 13, wherein said surfaces of said pocket are connected by sealing. 22. A method for making a parachute canopy from a suitable gore material comprising the steps of:(i) creating a pocket in an interior side of at least one of a plurality of gores having interior and exterior sides by a step selected from the group consisting of folding, gathering and folding and gathering a piece of said gore material into a plurality of surfaces which together form a polyhedral configuration;(ii) connecting said plurality of surfaces of said folded, gathered or folded and gathered piece of gore material to form said pocket, and(iii) connecting said plurality of gores together in at least two places along sides of said gores. 23. The method recited in claim 22, wherein the plurality of surfaces of said pocket form a trihedral shaped pocket. 24. A method for making a parachute canopy from a suitable gore material comprising the steps of:(i) creating a pocket on an interior side of a plurality of gores having interior and exterior sides, said interior sides of said gores formed into said pocket by a step selected from the group consisting of folding, gathering, and folding and gathering a piece of said gore material for forming a pocket configuration;(ii) connecting surfaces of said folded, gathered or folded and gathered gore material of a given gore to form said pocket configuration, and(iii) connecting said plurality of gores together wherein each gore is affixed to an adjacent gore at least at two spaced locations.
