A noble effort from a noble company with a noble heritage.
They made an impressive and largely workable effort but merely 'workable' simply didn't cut it in that arena at the time.
It took a just one engine, not 10 to show the world how.
A lesson no one has recalled or exceeded until quite recently, and even then I await being really persuaded...
Still, I doff may cap to thse guys. They pushed the technology along and with some elegance too.
