This is the dumbest thing I read on this thread.
There is a reason the speed limit is 120km/h and not 200km/h. Yes I can drive 200km/h and probably nothing will happen. But if a tyre burst or something run in front of me, I am probably dead and might kill others. Your time to react is so much shorter and near impossible. 120km/h I may still save it.
In Urban areas its 60km/h because there are even more danger/risk with people and kids walking, riding bicycles etc.
There is a reason pilots don't fly over crowds at air shows. We have air shows all over the world and rarely something goes wrong. But they are taking bigger risks than normal and thus have to keep clear of crowds if something may happen.
So yes, flying that low increases the risk substantially if something goes wrong. Recovery chances is very low. And we not talking one or two in a car and maybe a few other in another car that may die. We talking tens of thousands that can die.
Nope. This is officially the dumbest thing I have read in this thread.
Speed limits exist because roads are physically engineered with specific safety margins in mind. Look at the German Autobahn it is unrestricted, yet it is statistically one of the safest highway networks in the world. Because the infrastructure is built to support those speeds. Cars are thoroughly designed, tested, and rated to handle high velocities.
Standard speed limits are set for the lowest common denominator on the road the average family sedan under average conditions. It's a tool for collective risk management, not a metric of what a car can mechanically achieve.
The US imposed a nationwide 55 mph maximum speed limit in 1974, largely as an energy-conservation measure during the oil crisis. It wasn't a case of dropping speed limits. Some states subsequently raised their limits, and the federal mandate was eventually repealed in 1995.
60 km/h is absolutely not a speed at which a pedestrian can reasonably be described as safe. Collision severity rises exponentially with impact speed, and the probability of fatal or severe injury becomes dramatically higher than at 30 km/h
Your aviation example is just as daft. Planes fly over crowds all the time. What they don't do directly over crowds is high-G aerobatic maneuvers.
The Airlink flight didn't involve high-G stunts. The aircraft maintained a straight approach path that was established kilometers out, and they only initiated their turn after clearing the stadium.
I’ll let you in on a little secret.
A meticulous flight plan had to be submitted to ATNS and the SACAA for strict legal approval, detailing exact altitudes and speeds. The flight was planned precisely for those altitudes. Because there were two aircraft involved, they had to fly in a staggered formation specifically so the second jet wouldn't get caught in the dangerous wake turbulence of the first. That is basic fluid dynamics.
If they had flown at a significantly higher altitude, the staggered height differential would have pushed the trailing aircraft completely out of alignment for the presentation, these flights are planned weeks in advance, heavily simulated.
This is much ado about nothing......
