I live near an airport and this morning a plane was circling the town 6 times but still was landing for few seconds but flying away again . And this thing happens often in our small city .Any opinions?
Sounds like someone was doing a touch-and-go landing. This is usually done when learning to fly an aircraft, to be able to practice a number of landings in a short time window. If there is a flight school at your local airport, this might explain why it happens a lot.
