  • H25B / AS29, en-route / manoeuvring, near Smith NV USA, 2006 (Synopsis: On 28 August 2006, a Hawker 800 collided with a glider at 16,000 feet in Class 'E' airspace. The glider became uncontrollable and its pilot evacuated by parachute. The Hawker was structurally damaged and one engine stopped but it was recovered to a nearby airport. The Investigation noted that the collision had occurred in an area well known for glider activity in which transport aircraft frequently avoided glider collisions using ATC traffic information or by following TCAS RAs. The glider was being flown by a visitor to the area with its transponder intentionally switched off to conserve battery power.)
  • F16 / C150, vicinity Berkeley County SC USA, 2015 (Synopsis: On 7 July 2015, a mid-air collision occurred between an F16 and a Cessna 150 in VMC at 1,600 feet QNH in Class E airspace north of Charleston SC after neither pilot detected the conflict until it was too late to take avoiding action. Both aircraft subsequently crashed and the F16 pilot ejected. The parallel civil and military investigations conducted noted the limitations of see-and-avoid and attributed the accident to the failure of the radar controller working the F16 to provide appropriate timely resolution of the impending conflict.)
  • G115 / GLID, en-route Oxfordshire UK, 2009 (Synopsis: On 14 June 2009, a Grob 115E Tutor being operated by the UK Royal Air Force (RAF) and based at RAF Benson was conducting aerobatics in uncontrolled airspace near Drayton, Oxfordshire in day VMC when it collided with a Standard Cirrus Glider on a cross country detail from Lasham. The glider was sufficiently damaged that it could no longer be controlled and the glider pilot parachuted to safety. The Tutor entered a spin or spiral manoeuvre which it exited in a steep dive from which it did not recover prior to a ground impact which killed both occupants.)
  • AS50 / PA32, en-route, Hudson River NJ USA, 2009 (Synopsis: On August 8, 2009 a privately operated PA32 and a Eurocopter AS350BA helicopter being operated by Liberty Helicopters on a public transport sightseeing flight collided in VMC over the Hudson River near Hoboken, New Jersey whilst both operating under VFR. The three occupants of the PA32, which was en route from Wings Field PA to Ocean City NJ, and the six occupants of the helicopter, which had just left the West 30th Street Heliport, were killed and both aircraft received substantially damaged.)
  • C525 / P180, south west of Sion Switzerland, 2012 (Synopsis: On 22 March 2013, a Cessna 525 inbound to Sion on a VFR clearance was flown into conflict with an IFR Piaggio P180 departing the same airport in compliance with its clearance and the prescribed separation between the two aircraft was lost in the vicinity of FL140. The Investigation concluded that an inappropriate ATC tactic had been employed in an attempt to achieve separation and recommended the development of a new procedure to better facilitate separation between IFR and VFR traffic in the airspace where the conflict occurred.)
