This is a rather unique was to delay a flight.

Man Sucked Into Airplane Engine
Witness: 'He threw himself against the aircraft's engines'
According to what has been ascertained so far, the victim would have voluntarily entered the operational area of the airport with the intent of taking his own life.
The man, who was neither a passenger nor an airport employee, reportedly reached the runway by evading security checks and running towards the already moving aircraft.
The police, who had noticed his movements, were unable to stop him in time.
"We saw this gentleman running away from the stewards, at first he threw himself against the casings, the protections of the right engine of the plane, then he went around and either threw himself or was sucked into the impeller of the left engine: so what happened happened". One of the witnesses of what happened this morning at Orio al Serio airport is still shaken, where a thirty-five-year-old was sucked into the engine of an aircraft and died. Whether it was a voluntary act "I don't know" he added. The person who saw what happened was boarding the plane next to him. "We were trying to go up the stairs and we saw everything" he says. A story that can only be raw. The passengers then remained on the plane while the firefighters and police arrived. About fifty minutes in which they were explained what was happening before being made to get off because their flight was cancelled. "We got off, we got our bags and now we are here" he concluded.
