“landing” includes alighting on water;
“military service” includes naval and air force service;
“unlawfully”, in relation to the commission of an act —
(a)in Singapore, means an offence that is (apart from this Act) constituted under any written law in force in Singapore; and
(b)outside Singapore, means the commission of the act that would (apart from this Act) have been an offence under any written law in force in Singapore had it been committed in Singapore.
(2)  For the purposes of this Act —
(a)the period during which an aircraft is in flight shall be deemed to include any period from the moment when all its external doors are closed following embarkation until the moment when any such door is opened for disembarkation, and, in the case of a forced landing, any period until the competent authorities take over responsibility for the aircraft and for persons and property on board; and
(b)an aircraft shall be taken to be in service during the whole of the period which begins with the pre-flight preparation of the aircraft for a flight and ends 24 hours after the aircraft lands having completed that flight, and also at any time (not falling within that period) while, in accordance with paragraph (a), the aircraft is in flight.
Hijacking
3.—(1)  Subject to subsection (2), a person on board an aircraft in flight who unlawfully, by the use of force or by threats of any kind, seizes the aircraft or exercises control of it commits the offence of hijacking, whatever his nationality or citizenship, whatever the state in which the aircraft is registered and whether the aircraft is in Singapore or elsewhere.
(2)  If the aircraft is used in military, customs or police service, subsection (1) shall not apply unless —
(a)the person seizing or exercising control of the aircraft is a citizen of Singapore;
(b)his act is committed in or over Singapore; or
(c)the aircraft is used in the military, customs or police service of the Republic of Singapore.
(3)  A person who commits the offence of hijacking shall be guilty of an offence.
Violence against passengers or crew
4.  Any act of violence against the passengers or crew of any aircraft in flight done by any person in connection with the offence of hijacking committed or attempted by him on board that aircraft shall be deemed to have been committed in Singapore and shall constitute an offence punishable under the law in force in Singapore applicable thereto, wherever the act of violence was committed, whatever the state of registration of the aircraft and whatever the nationality or citizenship of the offender.
Destroying, damaging or endangering safety of aircraft
5.—(1)  Subject to subsection (4), any person who unlawfully and intentionally —
(a)destroys an aircraft in service or so damages the aircraft as to render it incapable of flight or as to be likely to endanger its safety in flight; or

shall be guilty of an offence.
(2)  Subject to subsection (4), any person who unlawfully and intentionally places or causes to be placed on an aircraft in service any device or substance which is likely to destroy the aircraft or is likely so to damage it as to render it incapable of flight or as to be likely to endanger its safety in flight shall be guilty of an offence; but nothing in this subsection shall be construed as limiting the circumstances in which the commission of any act —
(a)may constitute an offence under subsection (1); or
(b)may constitute attempting or conspiring to commit or abetting the commission of the offence.
(3)  Except as provided by subsection (4), subsections (1) and (2) shall apply whether any such act therein mentioned is committed in Singapore or elsewhere, whatever the nationality or citizenship of the person committing the act or whatever the state in which the aircraft is registered.
