TWA Flight 891 was a Lockheed L-1649A Starliner that crashed not long after taking off from Milan Malpensa Airport on 26 June 1959.

On 26 June 1959, TWA Flight 891 departed Malpensa Airport in Milan, Italy, with a crew of 9 and 59 passengers on board.

When Flight 891 departed Milan, light rain was falling with a low overcast and a ceiling of around 2,000 feet, with visibility of approximately two miles (3.2 km).

[6] On 24 November 1960, an Italian inquiry board announced its finding that a lightning strike had brought down Flight 891.

In the absence of other significant concrete evidence, taking into account the stormy weather conditions, with frequent electric discharges, existing in the area at the time of the crash, it may be assumed that the explosion of the fuel vapors contained in tank #7 was set off, through the outlet pipes, by igniting of the gasoline vapors issuing from these pipes as a consequence of static electricity discharges (streamer corona) which developed on the vent outlets.
