I have this one. Lined up a couple of launch & orbital testing contracts along with this one for reentry, but didnt notice the velocity restriction.. wondered why I didnt complete the contract after engaging parachutes at over 1000m/s. D'oh! Got the rest of them though Only just started my career, so the zaniest thing I've had to test was a inline separatron at launch. Just strapped it underneath my first stage and with the aid of launch stabilisers was away!
