Good Morning from Central Texas.
At 6am is 44 degrees, headed to mid 50's. Later this week in the 70's !
The USAF (with Lockheed Martin Skunk Works) is developing the SR-72 Darkstar replacement for the SR-71 Blackbird. Speed is claimed at greater than mach 6 (or about 4,600mph) with a ceiling of 85,000 feet (or about 16 miles high) - proposed hypersonic reconnaissance and strike aircraft.
Is this it ? Cannot confirm.
Hope all have a great day.
