Well, anyone heard of St Maarten's Juliana International airport ? Aeroplanes fly at super low levels here. This is because separating the beginning of the runway and the beach ( as u would see in the videos below) is just a mere two-way street with one line in each direction, and the airport parameter fence. Also, the runway is short - at 2100m , which is less than the 2.4 km we run for our napfa test , and thus for giant planes like boeing 747s to land, they cant afford to be airborne over the runway for too long. Or else, they would overshoot the runway.
In fact, the minimum landing requirement for such planes is similar to the length of the runway itself. So , u could imagine that kind of precision the pilot needs to ensure a safe landing. This also means that they have to touch down as soon as they reach the runway, so that they reduce the time they spent airborne over the runway. So , tats why aeroplanes have to fly low on final. I wont be surprised if u ever put one double decker bus on the road, it will hit the lower part of the landing gear. But then again, its St Maarten- a small island that is part of the Netherlands Antilles. So u wont find such buses there. The first video shows a plane landing low on final. The second one shows pictures of planes landing low on final. All at St Maartin's Juliana International Airport. Enjoy!
