As a year ago, the trip to the United States began a week after the start of the holiday, but this time the number of participants was greatly increased, in addition to Darren, Hermione and Penelope, there were also Granger and Penelope's family. Pen & Fun & Pavilion www.biquge.info

Of course, when going through the relevant procedures, Darren, who was reading the newspaper, also unexpectedly found that there was a very good reason to use, the Olympic Games, now in 1996, the 26th Summer Olympics, and the 100th anniversary of the birth of the modern Olympic Games, was held in Atlanta, USA.

Being able to take the Concord undoubtedly made everyone very excited, especially the famous "second sunset", which made them feel extremely magical, but, because of the difference in "travel reasons", this time they couldn't live together, no way, it was easy to explain that they were going to fly together by the way, if they even lived in the hotel together, or a five-star hotel, it would be too obvious! After all, it's always not easy to get people to the other side of the world for no reason, and there is no tomahawk at home, and Darren doesn't want to practice memory magic with ordinary people casually, even if he wants to cast a spell, he must not do it!

So, the Granger couple received an invitation letter from an American dental organization that said they had been selected to participate in a dental exchange program that would provide free business training, with "reimbursement" of all travel expenses, and "business loss expenses" during the training......

And the Penelope family is simple, as an elite who has successfully entered the top of a large company, because they have undertaken the company's expatriate business, so it is enough to bring their families to live in the United States, although the nominal party will soon leave the United States, but the rest of the people who stay here will only think that she was assigned to another city, the United States is very big, how to take a plane.

In this way, before Voldemort is completely dealt with, at least there is no need to worry about accidents in this regard, as for whether the Death Eaters will also chase after them, let those guys learn how to fly first, with their style, they will inevitably be taken down by the security guards, of course, it may also be the security guards who will be taken down, and then the Ministry of Magic will urgently dispatch memory erasers......

While settling their respective families, Darren was also busy with another new company, fortunately he had made enough money before, otherwise it would be impossible to open companies one after another, no way, there is a lot of money, it is capricious!

This company will be full-time to develop extremely high-altitude detection technology, as for what is the research direction, it is naturally a rocket, and it must be a solid rocket, a rocket with a very high thrust-to-weight ratio, just like a missile engine is the best, no way, it is too expensive to buy missiles directly, and it is not convenient.

In fact, Darren risked smuggling arms to buy missiles, largely because although the wizards' magic is magical, it is really far from the ultimate performance, otherwise Darren would not have had to go to great lengths to spend more than half a year in the Slytherin secret room under Hogwarts.

In that strike project, Darren finally used magic to solve the problem of target detection, data synchronization, locked tracking and other problems, and achieved very good results, but only when it came to the propulsion system, he really couldn't help it, because wizards have few physical high-speed movement functions, such as flying broomsticks, although they are very flexible, but even if it is known as the fastest fire ballista before, the maximum speed is not even comparable to some supercars, not to mention those fighters with perverted performance, although the intended target is not F16 or something, but at least it has to reach the level of Hellfire, then it is miserable enough, slower than 9mm pistol bullets。

What's more, the body that needs to be propelled is much heavier than the person on the broomstick, according to the final calculation, although it can't compare to Hagrid, but it is definitely compared to a dead trio, well, now it's a duo, that is, they are twice as heavy as the broomstick, and the performance of the broomstick is not enough at all.

As for the dragon fire on the flying motorcycle, the use of direct spraying like Blake is a serious waste, and most of the energy is released into the air without making full use of it, so Darren will not be so stupid, and how can the industrial base of the wizards' semi-handicraft industry be compared with ordinary people who have entered the industrialized society, and the output is completely impossible to meet the demand, and when the time comes, how can it be thrown away......

Therefore, the final result is very simple, Darren must establish his own supply channel for solid rocket propulsion systems, even if it does not reach the level of military performance, but it is more than enough to meet his requirements, even if he has the habit of "anticipating the enemy leniently", those predetermined targets cannot be coped.

In addition, although a country's large anti-hail rocket is also good, the size and weight of the current development system are a bit excessive, after all, the procurement of finished products is not as good as tailor-made, wait until the next step of the ground system is finalized.

With Darren's full promotion, or more precisely, a large amount of money, by the time Hermione and Penelope can go, the basic process of the new company has ended, and the rest is the specific business process, which can be transferred to Penelope to familiarize himself with, and the gun company is also in contact with her, and an extra salary is, oh, there should be shares, and good bosses know to fully mobilize the enthusiasm of employees......

Although it was purely for fun and didn't watch a few games, Darren felt that the Olympics were much better than Quidditch, at least people were really fair competition, which was like wizards, there were no restrictions on broomsticks at all, and when he put the "Super Broom" on the market, he would see how to play Quidditch!

After the end of the Olympic Games, Darren also just finished the business at hand, now, there is plenty of time to play, sit on the yacht, and if it is really successful, it is necessary to go to the sea, of course, it is to "swim" to play, this is also one of his goals this time, for it, Darren spent a lot of money, and finally drove out the equipment needed, even if there has been a successful trial in front, but this time the requirements for perspective and imaging are too high, so it is almost a new product specially developed for orientation.
