I spent several years designing control systems for rocket/spacecraft control, all done with computer control of course, some contributed to the ESA. Britain is very highly regarded for it's software engineering. But I must say that if the actual real engineering wasn't up to scratch then no matter how clever your control design, if you didn't have the excellence of British engineered components then you didn't have the feed back and the control needed. So don't ever forget the skills we have here on both sides of the coin.
