Good thing the Cessna pilot in the first video didn't live here in the States because the FAA would pull his/her ticket faster than it takes to preflight that plane. No waiver to fly that low, not higher than the highest obstacle in the area flying too close to people for starters. The third video isn't due to high winds, this is a Bush pilot flying a highly modified plane with a low wing loading, leading edge slats and full length flaps. Built to take off and land in extremely short distances found off in the wild. There's competitions for this, it's common to see them take off and land in around 10 feet. The pilot flying the helicopter with the water bucket does ot know what his doing. The buck has weights on it so it sinks quickly and the helicopter approaches then lifts off almost continuiose motion. I flew a bucket under UH 1 for several days at the Atlanta Federal Prison when the Cuba torched the industrial building.
