Supersonic drones, do you think they will be used to deliver express delivery?

Lin Yu, the second generation of rich people: “I want to participate in the technology venture capital meeting in half a year, so I would like to ask you to help me design a large drone!”
Chen Mo: “Do you have any requirements?”
Lin Yu thought for a while: “Second One needs to be bigger, and the second needs to be faster. I plan to use it to deliver express delivery in the future, so the carrying capacity is much greater.”
Chen Mo nodded: “Okay, it needs to be big and fast, and the carrying capacity is much greater.”
Half a year later, Z Big Technology Venture Capital Conference.
When a large drone with a total length of 20 meters, a height of 6 meters and a wingspan of 30 meters breaks through Mach 1.5 at an altitude of 10,000 meters.
Everyone looked up at the white track in the sky, dumbfounded.
At the venture capital meeting, an international friend from Camel Country came to our door curiously, wearing a white headscarf.
Lin Yu: “No, no, no, you can’t mount anything on the wing. Didn’t you buy it back and deliver it by express delivery?”
Chen Mo: “It can mount 20 LJ-7s.”
Lin Yu: “If you can’t put it in the cabin, mushrooms will grow. Guys, what are you doing after buying it back? Hey!”
Chen Mo: “It’s not impossible to put it away.”
Lin Yu: “Chen Mo, are you sure this thing is for express delivery?”
Chen Mo said seriously: “Yes, it is for express delivery. , if someone says otherwise, you can sue him for defamation.”
An international friend said: “Can we buy a few? We have a group of robbers coming over to rob our oil.”
