My list…

1. Boeing 314 flying boat…probably from San Francisco to Hong Kong
2. The Hindenberg across the Atlantic
3. Douglas C-124…yes I know it’s not commercial but I’d love to cross the Pacific on the flight deck of one.
4. Concorde
5. Constallation
6. Lockheed Vega or Orion…not to picky
7. Lancastrian of BSAA
8. A Trilander to somewhere exotic
9. A KLM DC-2 from Amsterdam to Batavia
10. A TWA Ford Tri-Motor on the air-rail transcontentintal service.
11. AW Argosy (biplane)
12. Viscount

I’m not that old…but I count myself lucly to have flown across the Pacific to Tokyo in an ancient DC-6, and back in a new 707.

A few years ago the Boeing Model 40 would have been on my list, but I’ve flown in (and helped restore) the sole airworthy example.
And I finally got my DC-3 ride. Not an American Airlines Flagship, but close enough.

Is that a typo?

My list would be Concorde and Caravelle. Vanguard, Bristol Britt. Oh, and a Connie.

😮 wrong ! physics , Go read . 🙂

I read too deep, Earthling.

Another conundrum.

The “Force” of gravity. What if it has a polarity? A bit like electric?
What happens if there is an opposite polarity somewhere? A repel attract repel situation.
……I’ve not opened these books since skool!

Wrong
Gravity is the weakest of all the forces, but is one of the hardest to overcome

Ah, but mathematically it is the weakest of the 4 fundamentals, but it still carries the force to pull on a Rock several billion light years away. Yet you can hold that rock and lob it vertically if on Earth.
The collective forces of the centre of the Galaxy should mathematically be powerful enough to be reversing the bang. But they aren’t..yet. Do we know for sure that if we travel to the centre of our Galaxy, we would be crushed by the extra force, which should be present in the middle?
The Newtonian sums give differing results for a Fly or an Elephant due to mass. Yet both feel 1g and both can very easily overcome it.

I think we’ll get more than 6 months.

Today’s “In Space” telescopes are picking up Black-cats-in-coal-cellars” at the edge of the known uni.
However, they are often looking at the wrong part of the sky LoL! How many times does an amatuer astronomer find something odd, report it to the appropriate astro sites…..then suddenly all the Dishes in the world turn 180 LoL.

PeeDee and PNM as your both a pair of clever S*** now tell me just how large this sail would need to be to move an incoming about 2 miles in diameter.!950s camera flash PeeDee, you showing your age now. 😀

Lincoln .7
:diablo:

Think BIG. Now double it.
The particles of light hitting the sail will give a force. So, estimates as to the size would be measured in Acres. But they are very thin, a couple of thou., so they can be packed up correctly to fit in, shall we say, a “Buildable” spacecraft.
Think not of the weight / mass and speed of the incoming, it is on a path which is pulled by gravity of the sun, and only a slight force is required to overcome gravity, as you clearly demonstrate by shining your pants right now.
Some Satellites already use them to correct minute trajectory alignments. I think the Japs have launched a bug-un too.

Gravity, the most powerful force in the Universe, yet we can very easily overcome it. Pity we don’t actually know what it is.

If all we had was 6 months then the best we (as a species) could hope for would be to build some bunkers to try to preserve what life we could to re-populate the earth, assuming of course they would survive the strike.

I have seen lead times varying from 10-25 years when it comes to deflecting an asteroid, either with sales of a chain of nuclear charges.

Read up on “Don Quijote” (Not my mispelling!).
