Yes, SpaceX needs to purchase tickets for its upcoming SpaceX mission.
SpaceX has launched the "Dragon 9" rocket on a SpaceX Falcon Heavy rocket into orbit with four tourists, including NASA astronaut Anne McClain and other passengers on the spacecraft 'Dragon'. Additionally, there are also American real estate开发商 Larry Hennessy, Canadian Mark Pecies, and Israeli businessman Ilan Steitzer aboard the spacecraft.
Can high-altitude flying boats replace search and rescue planes?
Regarding this question, let me take a look at it from the following aspects:
1. Flying boats can maintain滞空 time for several months, which is longer than the hover time of warning planes, but the current flying boats are mainly used as detection devices rather than personnel, so their capabilities are not very comprehensive compared to warning planes.
2. Flying boats move extremely slowly, which means that they usually perform missions in border regions and act as a fixed surveillance station similar to a radar station above the sky. This is in contrast to warning planes, which are more flexible and can be deployed according to tasks as needed, resulting in higher efficiency compared to flying boats.
3. Most modern flying boats use pressurized helium instead of compressed air to ensure safe deployment in high-altitude areas. They also often use aluminum foil to protect against harmful UV rays, and have basic structures for supporting their own weight. In terms of cost, the development and procurement costs of modern flying boats are generally not as low as one might expect, and actually, the price is relatively expensive.
4. Another point to mention is that flying boats like these are considered "dishes" in the aviation industry, looking good from afar but having several disadvantages. The advantages include being able to provide certain functions such as data collection and monitoring, but the drawbacks include being less efficient than satellites or other aerial vehicles and being less practical in remote areas where traditional ground-based assets may not be available.
Overall, while some people may view flying boats as useful tools, they are mainly research products and will not be widely deployed unless they meet specific requirements from users.
