An automated system called Minimum Safe Altitude Warning alerts air traffic controllers if a plane goes too low.On an air traffic recording, a controller can be heard saying: “Southwest 4069, low altitude alert. You good out there?”

The FAA did not specify how close the plane came to the ground, and the pilot's response was not included on the audio recording, but FlightRadar24 used atmospheric and flight data to estimate that the craft came within about 525 feet of ground level.The plane landed safely shortly afterwards.In a statement Friday, Southwest said it is in contact with the FAA “to understand and address any irregularities with the aircraft’s approach to the airport.”

The FAA is also investigating a Southwest flight that came within about 400 feet of the ocean off of Hawaii during poor weather conditions in April.The pilot of that plane bypassed a landing at Lihue airport and inadvertently caused a rapid decent, according to a company memo. The plane, a Boeing 737 Max 8, returned to Honolulu. Nobody was injured.

In May, a Southwest flight en route from Phoenix to Oakland experienced a “Dutch roll” – a potentially dangerous side-to-side movement across two axes.

Nobody was hurt but the plane, also a Boeing 737 Max 8, was damaged, and the National Transportation Safety Board is investigating."When potholes are very close to the edge of the road it makes it difficult to cycle there, so you have to cycle more into the middle of the road and that irritates the drivers."

The issue has also been flagged by Mr Stewart, who said he had noticed an increase in damage caused by potholes, adding: "In the bike shop we get a lot of cyclists coming in with damaged wheels and punctures where they've hit potholes."It's a real problem."

Miguel Gentil Fernandez, an avid cyclist from Wollaton, is an associate professor at the University of Nottingham, specialising in urban planning."All along Derby Road, it's very very dangerous for cyclists," he noted.
