Investigators believe a bomb probably caused an onboard explosion that forced an Airbus A321 to return to Mogadishu and make an emergency landing.
One man was killed in the blast on the Daallo Airlines jet on Tuesday.
Two passengers were injured.
Local authorities north of the Somali capital say the body of a 55-year-old man was found in the area.
He is thought to have been sucked out through the hole in the fuselage.
Somalia’s deputy UN ambassador Awale Kullane filmed the drama on his smartphone:
“I heard a big bang and the smoke erupted, so we did not see anything for a few seconds.”
“It was scary and everyone was a bit traumatised in those few seconds.”
Experts have praised the actions of the crew in landing the plane with so few casualties.
There has been no immediate comment from al Shabaab, the Somali Islamist group that is engaged in an insurgency in the country.
It has carried out regular attacks on officials, government offices and civilian sites.
