That's right, rockets. With explosives. Me, pilot in training, foreign airplane, foreign flight instructor, flying cross-country, with explosives in the back-- hey, no pressure! Actually, EVERY Cirrus has an explosive rocket in it, that's how the parachute deploys. We just happened to have three. And, since you are reading this, you know that we survived me handling the extra power that an SR-22 has over an SR-20. Wow, the take-off was wild! I pushed the throttle up and it felt like those rockets had launched.
