building a jet rocket in Kerbal Space Program

I built a jet-engine-powered rocket in Kerbal Space Program. I tried to get as far from the Kerbin surface as possible flying straight up. I achieved an altitude of 171.7 kilometers (106.7 miles). The top speed was 1,498 m/s (3,351 mph) at about 16 kilometers (52,000 ft) and the top acceleration was over 15 g at about 5 kilometers (16,000 ft).

I played on Hard difficulty on 64-bit Windows version 1.3.1.
