Official investigations

A British Court of Inquiry convened on 7 July that year investigated the crash of Sikorski's
Liberator II serial ''AL 523'', but was unable to determine the cause, finding only that it was an accident and "due to jamming of elevator controls", noting that "it has not been possible to determine how the jamming occurred but it has been established that there was no sabotage."
The Polish government refused to endorse the report, due to the contradiction about the cause not being determined but sabotage being ruled out, and pursued its own investigation, which suggested that the cause of the accident cannot be easily determined.
The political context of the event, coupled with a variety of circumstances, immediately gave rise to much speculation that Sikorski's death had been no accident, and may have been the direct result of a German, Soviet, British, or even Polish

(IPN) began an official inquiry into the incident.
Sikorski was exhumed and his remains were examined by Polish scientists, who in 2009 concluded that he died due to injuries consistent with an air crash and that there was no evidence that Sikorski was murdered, ruling out theories that he was shot or strangled before the incident; however, they did not rule out the possibility of

In 2013 one of the IPN historians, , has stated that "many facts suggest an assassination", although another,
Andrzej Chwalba, notes that there is insufficient evidence to support this claim. He also complains that some British and Spanish documents still remain classified, hindering the investigation.
The Polish investigation ended in 2013 with the conclusion that deliberate tampering to the aircraft could be neither confirmed nor ruled out.

'' in 1997, as no conclusive evidence of any wrongdoing has been found, Sikorski's death remains officially classified as an accident.

Conspiracy theories

, in his ''Historical Dictionary of Poland'' (1996) entry on the "Gibraltar, Catastrophe of", notes that "there are several theories explaining the event, but the mystery was never fully solved."
For example, there has been uncertainty since the day of the crash about who boarded the plane and about the exact cargo manifest—all leading to uncertainty as to the identity of the bodies recovered from the crash site; some bodies, including that of Sikorski's daughter, Zofia, were never recovered. Since several bodies were never found and the bodies of several members of Sikorski's entourage were never positively identified, some conspiracy theorists such as journalist and amateur historian Dariusz Baliszewski postulate that some might have been murdered on the ground while others might have been abducted to the Soviet Union.
Baliszewski and are among those who focus on the opportunity the Soviets had at Gibraltar. At about the same time that Sikorski's plane was left unguarded at the Gibraltar airfield, a Soviet plane was parked nearby; it carried Soviet ambassador Ivan Maisky, giving the Soviets an officially confirmed presence at the site of the accident.

Another controversy surrounds the sole survivor of the flight, a Czech officer, Eduard Prchal.[ Prchal, like many pilots who did not wish to tempt fate, was known for never wearing his Mae West life jacket—but on this occasion, when rescued from the sea, he was wearing one.] During the inquiry, he denied this, and later blamed the inconsistency on post-crash shock affecting his actions and memory—essentially, on amnesia

Polish aviation expert created a simulation of the crash, in which he concluded that the plane must have been under control up until the very moment of the crash.

published a book dedicated to the crash, in which he suggested British complicity in the incident. Irving's book highlighted what he believed were two other suspicious occasions where assassination attempts may have been made on Silorski during aerial flight, including a crash-landing in Montreal in 1942, where sabotage was a suspected cause. Irving's method and selective use of sources have been the subject of significant criticism.
In his book ''Disasters in the Air'', former KLM pilot and one-time IFALPA president Jan Bartelski, of Polish origin, suggests that the crash of the Liberator that carried Sikorski was caused by a half-empty mail bag jammed between the horizontal stabilizer and the elevator, thus "freezing" the controls and preventing Prchal from gaining altitude after takeoff. The mail bag was in the cargo compartment and was blown out of the aircraft through the side hatch (which in normally configured Liberators would have served to protect the machine gun position) by a strong airflow rushing through the nose gear door.
In popular culture
The crash of Sikorski's Liberator is portrayed in the 1958 film '' The Silent Enemy'', in which the team of Royal Navy divers charged with retrieving Sikorski's briefcase from the wrecked aircraft is led by Lionel "Buster" Crabb, himself later to disappear in 1956 in mysterious circumstances while diving in the vicinity of a visiting Soviet

was involved in plotting Sikorski's death. In Hochhuth's play, the plane is internationally sabotaged and Sikorski and the other passengers are murdered by axe-wielding commandos.[ Hochhuth, unaware that the plane's pilot Eduard Prchal was still alive, accused him of participating in the plot. Prchal won a libel case that seriously affected the London theatre which staged the play. Hochhuth never paid the £50,000 damages which the court ordered him to pay and subsequently avoided returning to the UK.] In 2011, he revealed his source for Churchill's involvement as Jane Ledig-Rowohlt, the British wife of his publisher Heinrich Maria Ledig-Rowohlt (née Jane Scatcherd). According to Hochhuth's biographer Birgit Lahann, these rumours relayed by Jane Ledig-Rowohlt had been the sole source for the allegations in the play.
In 2009, a Polish film, '' Generał. Zamach na Gibraltarze'' was filmed; the film focused on a plot to assassinate Sikorski.
