Yes, obese passengers have caused air crashes before. The most infamous one I can think of was a Cessna Caravan 208 that crashed in Pelee, Ontario. The findings of the report showed that the average passenger weight was 240lbs in that flight, whereas the airline was using an average weight for men of 188lbs at the time, which contributed to the aircraft being over 500lbs than estimated. This is a bigger issue with small aircraft, where your weight margin is much tighter.
Also note that passenger weight doesn't only include his body weight - it also includes all his carry-on belongings and clothings. Which is another reason a party of hunters with heavy winter clothing and hunting gear can weigh significantly above average as in the above crash
If it was above his property and below 500ft, the drone was trespassing. You own the airspace above your property, up to where FAA regulated airspace begins. Which is why New York property owners are able to sell the air above their property through air rights for millions of dollars.
Perhaps the property owner was reckless with firing a shotgun, but the drone operator should in the very least be charged with trespassing.
Not to mention that most of the railway trackage that would have to be built, in both the Russian and the American sides, would be mostly going through permafrost. Permafrost is not the most stable foundation for a railway bed - when the Chinese built the Qinghai-Tibet railway they had to include passive cooling with ammonia refrigerant to keep the soil at a stable temperature, and avoid warping of the tracks. And even then, they are running the risks of having to reconstruct the permafrost section of the track due to unanticipated global warming effects. The chinese only had a short 500km section with which they had to contend with permafrost. The Russian-American railroad would have to contend with thousands of kilometers of permafrost.
And if there were really that much of a business case for a US to China railway connection, the same case could be argued for a China to Europe railway connection,which already exists. Yet despite being a more direct route to Europe than an ocean route, the existing Eurasian Land Bridge only carries 1% of the China-Europe trade. The vastly more expensive US to China connection would be an even more dubious business case.
The difference is that you own the property rights including air rights above your property up to 500ft, so any aircraft flying below that altitude above your property is trespassing. Ownership of air rights is an old and established concept from as far back as medieval roman law - "Cuius est solum, eius est usque ad caelum et ad inferos", or "For whoever owns the soil, it is theirs up to Heaven and down to Hell". In modern times a practical limit of 500ft has been established by the US supreme court for air rights above your property, in urban areas extending to 1000ft. This has been sufficiently established that one's air rights above your property can be sold, and in places like New York City can command large sums of money.
So whether the drone was 50ft or 200ft is irrelevant - he was still trespassing on his property either way.
They can afford it because:
1) They get a third of the number of foreign students that the United States attracts
2) German universities tend to be a "no-frill" affair, with large auditoriums, limited to no athletics programs, and none of the social life seen in American campuses, Most students tend to study locally, so generally there are no dorms. They are more comparable with American state colleges. This isn't a bad thing, in my opinion, but those who go to college hoping for the experience of the "college life" will be disappointed if they go to Germany.
