These canopy systems were specifically designed and engineered for conventional military operations. This round canopy is similar to those pictured. The actual specs are;

• The MC1-1 Parachute Canopy #11-1-900 allows soldiers to steer towards specific impact points on the drop zone in winds up to 13 knots. It is capable of supporting up to 360 lbs. The MC1 parachute consists of a parabolic-shaped canopy with 60 sq ft of canopy removed and steering gear attached which allows the parachute to rotate 360 degrees in either direction in about 8 seconds. These canopies are 35 ft in diameter and constructed of CG483 green ripstop nylon. Normal 400 lb test suspension line lengths of 22-25 feet have been used. Descent rates vary from 16-20 fps.
  The MC1 Troop parachute has been used for static line airdropping of personnel from as low as 500 feet MSL.
• The canopy has a nominal diameter of 35 feet and a projected or inflated diameter of 25.7 feet.
• Technical restrictions for this type of system;
  All-up Suspended Weight (AUW): 160 Kg (350 lb)
  Minimum Deployment Altitude: 150 M (500 ft) AGL

  These canopies have over 950 square feet of excellent parachute nylon material that can be used as Racing parachutes by removing gores until the X pattern is the right size for your car. Great material for Rocket parachutes, kids tents or car covers. makes one HUGE 35' Diameter shade canopy or attention getter by inflating with a big air blower, i.e. Stake several lines to the ground and point a BIG air blower up in the center. We used a similar T-10 with an electric silent air blower on a tall stand to cover our tables at a flea mart. It took a bit to set up, but wow was it an attention getter. I'll try to set it up again and take some pictures to add here.
