UK Airprox Board (UKAB)

A new report says two Piper Cherokee aircraft came within 25m of each other during training flights.

The UK Airprox Board hears the two aircraft came within 500ft of each other over a town.

The UK Airprox Board says the incident created "a risk of collision".

Investigators say there was a "serious risk of collision" but "providence" played a part in events.

A Spitfire and Cessna 340 came close to crashing at 1,900ft, a report finds.

The white object appeared "suddenly" and "narrowly avoided hitting the aircraft", report says.

The UK Airprox Board says there was a "serious risk of collision between the two aircraft".

Four F-15s came as close as 50ft (15m) to a glider flying over Norfolk, a report finds.
