1. A system comprising:
a first aircraft recovery parachute and a second aircraft recovery parachute having a first set of physical attributes optimized for a first set of conditions, wherein the first set of conditions comprises a high speed and a high altitude, wherein the high speed relates to a speed greater than a speed threshold, and wherein the high altitude relates to an altitude higher than an altitude threshold; and
a third aircraft recovery parachute having a second set of physical attributes optimized for a second set of conditions;
wherein in the event that the second set of conditions is satisfied, a third aircraft recovery parachute is deployed, wherein the third aircraft recovery parachute is larger than the first aircraft recovery parachute, wherein the third aircraft recovery parachute is larger than the second aircraft recovery parachute, wherein the second set of conditions comprises a low speed and a low altitude, wherein the low speed relates to a speed less than the speed threshold, and wherein the low altitude relates to an altitude lower than the altitude threshold; and
wherein the first set of physical attributes and the second set of physical attributes are different.
