The man who died after being sucked out of a Somali passenger jet in midair on Monday appears to have been the person who detonated the bomb, reports the Wall Street Journal.

Citing a diplomatic source, the Journal’s Heidi Vogt writes that the man was able to “bypass rigorous security screening in Mogadishu” by arriving to the airport in a wheelchair. The source said the man was loaded onto the plane in the wheelchair and then moved to a regular seat. Five minutes after takeoff he then would have detonated the bomb and been pulled through the resultant hole in the fuselage.

All other passengers survived the incident, meaning this ended up being closer to a Jackass stunt than a terror attack.
