12. The system of claim 11 , wherein the drawstring further passes through at least a fifth attachment guide member configured at an edge of the net and between any two adjacent attachment guide members of the first attachment guide member, the second attachment guide member, the third attachment guide member and the fourth attachment guide member.

13. The system of claim 1 , the drawstring having a first branch attached to a first location of the net, a second branch attached to a second location of the net, a third branch attached to a third location of the net and a fourth branch attached to a fourth location of the net.

14. The system of claim 13 , wherein the first branch, the second branch, the third branch and the fourth branch each pass across the net and through a central location of the net and connect to a tether.

15. The system of claim 1 , the system further comprising:

a tension-producing mechanism that provided the tension on the drawstring to cause the drawstring to close the projectile down.

16. The system of claim 15 , wherein the tension-producing mechanism comprises one of: a weight that is dropped, a separate weight that is launched, a rewind spool for a tether attached to the drawstring, a parachute attached to the drawstring, a block and tackle structure attached to the drawstring, and a reversal of the first flying vehicle.

17. The system of claim 1 , where the drawstring is attached to a tether which is attached to the first flying vehicle and wherein a momentum of the second flying vehicle upon impacting the projectile causes the tether to pull on the drawstring.

18. A projectile cartridge that is removably attached to a first flying vehicle, the projectile cartridge comprising:

a net;

a first weight attached to a first location of the net, the first weight being configured in a first receiving cavity of the projectile cartridge;

a second weight attached to a second location of the net, the second weight being configured in a second receiving cavity of the projectile cartridge;

a drawstring associated with the first location and the second location of the net; and

a tether that attaches the drawstring to the first flying vehicle, wherein upon firing the net, tension provided to the drawstring causes the drawstring to close down the net and cause the net to capture a second flying vehicle, wherein at least two of four corners of the net have configured thereon a respective attachment guide member through which the drawstring is pulled to close the net down to secure the second flying vehicle.

19. The projectile cartridge of claim 18 , further comprising:

a drawstring mechanism to initiate tension on the drawstring to capture the second flying vehicle.

20. The projectile cartridge of claim 19 , further comprising:

a third weight attached to the net, the third weight being configured in a third receiving cavity of the projectile cartridge that enables the net to capture the second flying vehicle; and

a fourth weight attached to the net, the fourth weight being configured in a fourth receiving cavity the projectile cartridge the net to capture the second flying vehicle.

21. A projectile cartridge configured to be removably attached to a first flying vehicle, the projectile cartridge comprising:

a net;

a weight attached to the net, the weight being configured in a receiving cavity in the projectile cartridge that enables a projection of the weight upon firing via a control system on the first flying vehicle; and

a drawstring configured with the net, wherein the drawstring, after the net being fired to capture a second flying vehicle and upon implementation of a drawing operation, draws in to close the net to enable a capture of the second flying vehicle in the net, wherein at least two of four corners of the net have configured thereon a respective attachment guide member through which the drawstring is pulled to close the net down to secure the second flying vehicle.

22. The projectile cartridge of claim 21 , wherein the weight comprises a first weight attached to a first location of the net, and wherein the projectile cartridge further comprises:

a second weight attached to a second location of the net;

a third weight attached to a third location of the net; and

23. A projectile cartridge configured to be removably attached to a first flying vehicle, the projectile cartridge comprising:

a net;

a weight attached to the net, the weight being configured in a receiving cavity in the projectile cartridge that enables a projection of the weight upon firing via a control system on the first flying vehicle; and

a drawstring configured with the net, the drawstring connected to a tether which is anchored to the first flying vehicle, wherein a momentum of a second flying vehicle upon impacting with the net causes the tether to pull the drawstring and close the net on the second flying vehicle thus capturing the second flying vehicle, wherein at least two of four corners of the net have configured thereon a respective attachment guide member through which the drawstring is pulled to close the net down to secure the second flying vehicle.

24. A projectile cartridge configured to be removably attached to a first flying vehicle, the projectile cartridge comprising:
