Flight AH1020, which was traveling from Algiers to Marseille, had to return to Algiers on Saturday after incurring a technical malfunction and declaring a mid-air emergency, news outlets reported.
A passenger plane sparked a massive mystery after it declared a mid-air emergency and then disappeared from tracking devices – before landing safely.
The Air Algerie Boeing 737-600 took off from Algiers this afternoon on a flight to Marseille but let out an emergency call shortly after take-off.
Flight tracking data showed the plane turning around and heading back towards the point where it took-off.
Before the plane arrived however, it disappeared from tracking systems sparking a mystery that lasted almost an hour.
Plane tracking site Flight Radar 24 listed the plane’s status as “unknown” before revealing to its followers that it did not believe the plan had crashed.
It was later revealed that coverage for ADS-B – a system where satellite navigation is used to determine a plane’s location – is limited in the area in which the plane ‘disappeared’.
Posting to Twitter, the group said: “We believe Air Algérie AH1020 to be a *coverage issue* NOT a missing aircraft. Our ADS-B coverage in Algeria is limited.”
Folks it did not crash ADS-b does not work below 17,000 ft in this area all planes wont show up. #AH1020

Moments later, media in Algeria announced the plane had landed safely in Algiers having suffered technical failure while thousands of feet in the sky.
The initial worries were sparked when the plane completely disappeared from a number of flight tracking websites.
While some flight enthusiasts claimed the plane may have not been picked up below 17,000ft if it landed safely, Others have expressed surprise that no news of the plane’s arrival back at Algiers had been released.
The flight took off at around 1.30pm local time and was due to arrive in Marseille just after 4pm.
The plane in question has space for 123 seats – although it is not yet known how many were occupied by crew and passengers.
The fears came just days after an Emirates plane crash landed in Dubai.
Incredibly no passengers or crew were killed when the plane burst into flames as it skidded along the runway.
Tragically, one firefighter was killed as they attempted to put the raging blaze out.
