The most energy intensive stage of the launch is getting up in the air and gaining speed. Having it go off first decreases the time it takes to get up to speed and increases the flight range. Hauling the extra weight of the chemical booster could reduce the overall flight speed and range of the drone.

Having a booster rocket that is jettisoned adds a certain amount of inherent risk and complication. It needs to detach cleanly when it is finished every time. It also need to reliably remain attached during transport and launching.

The weight of the rocket equipment portion probably doesn't add up to much and can be compensated for with a slightly smaller warhead.

If I had to guess, it's likely a larger rocket motor from a common hobby rocket. Something like this or larger.

Plentiful, easy to source, and relatively cheap.

Yep, looks like the rocket stuck in the tube gave it a little push and the wheels were turned.

With a regular car, that netting acts as the perfect location for the drone to explode for maximum damage to the car and occupants. If you are on a suicide mission and want to make sure you all die, that is perfect.

It would potentially help an armored vehicle shrug off a few attacks.

Sounds like another construction job done with rampant corruption.

Designs call for 150cm thick cement walls with 15mm steel plates on the inside, it also calls for a minimum of 3m of dirt to cap it off.

After everyone takes their cut, they build a 50cm thick cement with 5mm thick steel plates and no dirt.

Hmmm... Guess what percentage of the owners who raise cattle voted for the orange moron?

98.5%, 99% or 99.5?

They are doing a reverse boat now. Water on the inside, dry on the outside.

What fertilizer have you used?

The S-300 is good platform to start from. They don't have to worry about proprietary technology like the patriot missiles. They can borrow all the best bits and modernize it a bit to make it potentially more effective.

Let's leave interacting with customers to an AI. It's known to have error rates and decision making ability of a drunken frat boy/sor girl. I am sure nothing will go wrong with that.

Mormonism.... Basically worse than all three.

If money is involved, there is always somebody who will trade.

When one party is untrustworthy, the other party figures out a way to mitigate their risks. Raising prices, reducing capital expenditure for the country, increasing insurance coverage, not offering credit (prepayment only) and diversifying their trading partners are common ways. All of these methods long-term fuck over the belligerent party.

The effects of this dumbfuckery will hurt the U.S. economy for 20+ years.

You can literally spend a lifetime researching the answers to your questions. Here is a very basic primer on the subject.

OP = open pollinated. This means that this is a population of related individual plants. These are produced by growing the parents in a large field and taking all the seed. Outcrossing, off types and variation is normal. Relative uniformity is maintained by roguing out off types.

Inbreds = are genetically mostly uniform (above 98%). These are used to produce OP's or F1 varieties . These are created by self-pollination, sib-pollination or double-haploid techniques.

F1 = A cross from two inbred lines. Most varieties grown from seed will produce fertile gametes with very few exceptions. Seed can be produced if you know how to. The reason F1's exist is because of heterosis or hybrid vigor. This makes the plants of some species (if bred corectly) healthier, more uniform, and produce more than OP or inbred lines. Saving seeds from an F1 will created and F2. F2 is the generation of maximum variation and the resulting plants will all be genetically unique.

Confusion of fertility of F1's: Sex expression in plants gets complicated. All male or all female plants are common in nature. Plants can also have separate male and female flowers on the same plant and all sorts of varietions. You can also change the sex expression of a plant with the application of some hormones. Plant breeders often take advantage of these diffences in variety development. Only varieties that have an odd number of chromosomes (like seedless watermelons) are truly sterile.

Saving seed - each species has its own techniques to successfully save seed. You'll have to research how to do it for everyone. Some are very easy to do like cantaloupes. Others can take specialized skill to save like lettuce.

Storing seed: Each species has its own storage requirements. You'll want to look up the requirements for each one. There are wide ranges of temperature and humidity. Some species can be stored for decades. Other species are only viable for a year.

Economics/risks of saving your own seed. Yhis gets extremely complicated fast as well. Seedborne diseases, pests, genetics etc all are parts to consider. There is no one size fits all answer.

My wife's fluffy white dog I drive around with for work. He likes to eat higher moisture corn and cow shit.

For silage corn the entire plant is harvested, chopped up, and packed tightly in a pile and covered with plastic or very large plastic bag. This creates an anaerobic conditions and yeasts/bacteria convert the sugars to alcohol, then acids. This acid preserves the feed for cattle for up to 2 years.

Silage corn is the most common base feed for all dairies and feedlots.

This isn't even the tallest variety out there. There are others that are 3' (1m) taller.

The machine with the spout is a chopper. They are a million dollar gigantic woodchipper. These things are fucking terrifying and you should absolutely stay out the field when they are running. Every so often a deer jumps into them.....shudder.... nightmare fuel.

Early in the season before a corn plant is waist high it takes a guess on how many kernals it can fill. Sometimes it guesses wrong and so it aborts the top kernals to fill the rest.

The entire top of the damn plant turns bright red.

As sugars build up in the top of the plant with no place to be transported to, the upper leaves start to turn bright red and die back.

You may get a bar bell ear or there may be no ear on the plant. In of field of millions of plants a bright red top narrows the search down.

Start getting your pinky in shape with this weird environmental triggered trait. It's easy to find in any corn field (to be continued...).

This right here is 350bu/acre of corn. 113 day variety on an almost pure sand field. Every damn ear looked the same. Look at that beauty, every kernal is huge and dense.

198

This here is trichoderma ear rot in an organic field. This 100 day variety was chewed on by an earworm. The damaged kernals allowed trichderma to enter and infect the ear. This ear rot produces many toxins and is a big no for consumption.

The twist - Trichoderma is usually a beneficial organism in the soil. It feeds on other pathogenic fungus/bacteria and is applied extensively for biological control.

Although normally a secondary pathogen, it has mutated to become a primary pathogen in both Italy and Germany in recent years.

98

This here is a genetically susceptible 113 day variety to fusarium kernal rot. This is a nasty little fungus that produces all sorts of mycotoxins that can give any mammal that consumes it a belly ache or even death. It's easily identifiable by the white streaks in causes in the kernals.

63

This 98 day little minx has a flirty pink cob. It doesn't look like much but it packs quite the wallop. The ears posted yielded 302bu. Medium high ear placement and a fast drydown makes this an excellent choice for grain.

72

This is pretty little 102 day number with a bright white cob that threshes very easily. It does extremely well for dry grain, high moisture grain or earlage.

The field in this picture averaged 305bu.

289

Probably the easiest plant to care for once you figure it out.

I water it every month or two. Fertilize it every 2 or 3 years. Redirect the arial roots into the pot when I water.

It gets 3 hours of direct sunlight in the morning.

Every 5 or 6 years I haul it outside in the summer. Then leach the pot with the garden hose to remove the salt buildup. I also hack the plant back to a more manageable size.
