Balloon goes u on UK made threaded inserts

摘要

A recent application has seen Fitsco's Screwfit brass inserts for plastics used as part of a project that takes a UK launched near-space craft clean through the troposphere and into the stratosphere, upwards of 40km, where air pressure is less than 1 percent of that at ground level and temperatures drop below -60℃. This is even higher than the 85,000' which the once top-secret Lockheed SR71 Blackbird is stated to have flown at.
