A major airport had to close a runway and divert all flights after a man's body was found on the tarmac.
The man met his tragic end at Murtala Muhammed International Airport in Lagos, Nigeria - which had to be shut down while an investigation was carried out.
International flights were unable to depart or arrive, with some turned away.
Officials are still working to identify the man and find how he ended up on the runway.
Initial reports suggest he may have been a stowaway who met his gruesome end after falling from the wheel-well of an aircraft taxiing to take off.
The man's body was found during a routine inspection, reports say.
Aviation security expert and former military commandant of MMIA Group Captain John Ojikutu said: “Nobody can say much now, but he may have been knocked down by the wingspan or undercarriage of a jumbo jet, but it is too early to say anything like that now.
He said the large residential area close to the airport could be a good place to start to identify the man.
He told news.com : “We need to examine the issue of houses that have been built too close to the Lagos airport,” he said.
“The rule says no building should be situated less than 6m to the airport structure or fence. However, we have seen cases of people crossing the runway before.
“The Nigerian Civil Aviation Authority and [Federal Airports Authority of Nigeria] need to investigate this to ascertain what really happened.
"They need to find out the flights that landed before that incident. The current airport perimeter fence is not a security fence and we need to do something about it.”
Another theory suggests the man fell from one aircraft the previous night before being crushed by another plane landing or departing.
In January, a stowaway who hid in the front wheel section of a cargo plane miraculously survived a gruelling 11-hour journey from South Africa to the Netherlands.
Dutch military police said that man was found after he had squeezed into the wheel section below the fuselage.
He was found 'doing well' despite the arduous journey after arriving at Amsterdam's Schiphol airport on Sunday.
Border control officers said in a statement: "The man is doing well considering the circumstances and has been taken to a hospital."
National police force Marechausse spokeswoman Joanna Helmonds said the man's age and nationality had not yet been determined.
"Our first concern of course was for his health," she said.
