My brother was a professional student.

My uncle was one such

Hardwood floors don't have any traction. I know this. I should have never watched Animal House.

I dodged the draft
or more correctly selective service

Jeez, remember student deferments (S1?) going away and sweating out the lottery?

No I was 17 and not caring

Boy talk about getting rid of the stress, thumbs up

I am down to my last 2 ounces! 4 custies stopped by today for an oz. each. Biz has not been like this in years. These last 2 ozs are gonna be gone tomorrow, I've got to dry my batch from 2 days ago super quick so I don't leave anyone hanging. My cash disinfecting box is always full these days, I think I have the most sterile cash this side of the US mint...

I was a 1-S. But my seeds are S-1's

Least they weren’t F-4s

Proof enough thrust will make anything fly. The glide ratio of a rock.

 

[tangerinegreen555]

I actually think I still have my draft card somewhere.

Does that count for real ID verification?

Who cares, I know who I am. Lol.

Still love that empennage negative dihedral.

I was 6 or 7!years old, Fenwick Island Delaware.

I saw some areobatic stuff some miles to the north. Young buck in a Phantom some miles to the north; Dover is the logical suspect.
I called my parents out just on time to see this young buck just tearing through the sky southward past our beach.
He was silent until maybe 20 degrees past our datum.
And then BOOMMmmm.
In German to my dad; wtf?
“ He broke the sound wall.”

I spent that day going up and down the beach hunting transparent cinderblocks.

The SR 71 had a double boom, I guess the nose and the inlet spikes were far enough apart to make separate ones.

The SR 71 had a double boom, I guess the nose and the inlet spikes were far enough apart to make separate ones.

My read on that is the speed was high enough on reentry interface that initial and recombinant booms were far apart enough hat you got two perceptible booms. Interval between initial and recombinant speaks to just how hypersonic.

The Shuttle did that kind of thing.

Lately there have been double booms here. Something massive is in reentry. No idea what.

Where you're at it's hard telling.

 

[cannabineer]

The SR 71 had a double boom, I guess the nose and the inlet spikes were far enough apart to make separate ones.

My understanding is that boom 1 was the bow shock, and that boom 2 was the shock from he displaced air smacking into itself.

That’s why the interval contained info about the boomer’s Mach number.

The second one from the SR was louder, which is why I was thinking the inlet spikes, with a larger area, created it. Just an uneducated guess.

I could be way wrong, but the spikes were too close to the bow shock cone.
So I’m left with positing a second shock center considerably aft of the ship.
Makes a tangible intershock interval.

I'll believe you Dr., my physics game is weak.

I must disclose that mine is worse than it was. So I listen more.
