It can now - but so did GRC initially. The critical question is, can it flex in 5, 10, 20 years time. Fortunately, thanks to an engineer's resistance to being bullied by commercial stupidity (and cupidity), PB were prevented from using GRC in structural members. Consequently, when it did all fail after 5 years, no-one was killed. If the Shuttle engineers had resisted as strongly 7 NASA astronauts would still be alive today. Frank
