1. When the propeller falls off
A Regional Express Airlines flight with 19 passengers flirted with disaster on Friday after one of its propellers fell off on the approach to Sydney Airport.
The spinning propeller was reported to have detached itself from the shaft and flown over the wing without touching the Saab 340 aircraft, the airline confirmed.
The plane landed safely but the Australian carrier has since grounded five other aircraft with the same propeller gear boxes and shafts from its fleet of 55 Saab 340s.
Those on board the domestic flight from Albury, around 500 kilometres (300 miles) from Sydney, were "lucky in the extreme" that the propeller had not crashed into the fuselage or tail of the plane, noted Paul Cousin, president of the Australian Licensed Aircraft Engineers Association.
2. The see-through engine
A San Francisco-bound American Airlines flight was forced to return to Phoenix last June after part of the plane’s engine cover fell off. An image of the damage was captured by a passenger.
The plane with 136 passengers on board landed safely at Phoenix Sky Harbour International Airport just 20 minutes after take-off and none were injured. Both American Airlines and the US Federal Aviation Administration are investigating the incident.
3. Terrifying turbulence
Last May, a video recorded on board an Etihad flight showed passengers praying for their lives after their plane encountered "severe and unexpected turbulence" during a journey from Abu Dhabi to Jakarta.
The clip, posted to Facebook by Dewi Rachmayani, shows passengers gripping their seats and screaming. Others can be heard shouting "Allahu Akbar" – an opening proclamation of every Islamic prayer. An air steward reportedly said: "I have been a flight attendant for 15 years, this is the first time I've experienced something like this."
4. Who left the door open?
Last year, a Korean passenger jet was flying at 10,000ft when it was discoverd that one of its doors was still ajar. Passengers captured the sound of rushing air and describing scenes of chaos on board.
Some reported nausea and ear pain during the flight, symptoms that resemble those reported during a slow loss of cabin pressure. Officials said there were no serious injuries or hospitalisations, though travellers were delayed by 15 hours.
14. Ryanair wings it
Not a high-speed collision this one, but it doesn't inspire passenger confidence when your pilot starts taxi-ing into other planes. This accident was filmed from on board an aircraft at Dublin Airport in October 2014.
15. Close call over New York
A mid-air near miss was recorded over New York in June 2013, between a Delta 747 and a Shuttle America plane near JFK Airport. At one point they were only 200ft apart.
16. Wings collide on Boston runway
A Delta jet is seen clipping the tail of a much smaller plane as it taxis down the runway.
17. Snake on a plane
Less hairy for passengers than it was for the poor snake involved, this video shows what happens when a Samuel L Jackson film plot comes to life.
