Ramjet

Inside of the Ramjet of the SR-71. The P&W J-58 could endure sustained speeds of Mach 3.2. The temperature limitations of the skin of the SR-71 was actually what restricted how fast the aircraft could travel.

It's called the Blackbird because black skin color maximized the radiative heat transfer of the aircraft.

It's not like those pumps are important or anything.

It is a mathematical certainty


Sometimes engineers have to explain to project managers their ideas don't hold water.

Get well soon

I sincerely hope my Congressman makes a full and speedy recovery.

Monumental

"I think it wisest not to keep open the sores of war, but to follow the example of those nations who endeavored to obliterate the marks of civil strife, and to commit to oblivion the feelings it engendered." - Robert E Lee

View of Cemetery Hill at Gettysburg

I decided to kind of do a 1 man reenactment of Pickett's Charge. I started near the Virginia monument, walked through the valley of death between Seminary Ridge and Cemetery Hill, then ended up near the Copse of Trees and the High Water Mark of the Confederacy. It's approximately the same route as Lo Armistead.  He was one of the few Confederates who made it to the Angle and through the first of 3 Federal Army lines. There he was fatally wounded. As he lay there bleeding out, he asked the Union officer who captured him how his best friend, General Winfield Scott Hancock was doing. The Union officer happed to be Gen. Hancock's​ Aide-de-camp and informed the dying Confederate officer (erroneously) Hancock had been struck dead. General Armistead expired.

Hancock was wounded and survived and would later become one of the first presidents of the NRA.

What struck me the most on my walk was how exposed I felt. There was no cover whatsoever and high ground everywhere. To attack ~8,000 dug in troops with ~15-20,000 (the later figure includes the artillery) across that ground was a suicide mission. I completely understand why Gen. Longstreet was nearly insubordinate in his attempts to get Robert E. Lee to change his mind.
