Concorde...

Its a bird..no its a swan...no..its a plane..no..its CONCORDE..the majestic bird with its characteristic deltoid wing..taking off on a trans-atlantic flight..photo via airliners.net..copyright Laurent Patry


A profile look of the now-grounded Concorde..shows the four air-intake valves fronting the Rolls-Royce engines that powered the bird. Pause for a moment and consider the marvel of engineering achievement in the air intake valves alone...when flying at Mach 2+, air coming in at about 1300 miles an hour has to be slowed down by about 1000 miles an hour in those short length tubes...yeah...amazing...
