"Squadron Leader Jackson, the first offence illustrates the absolute necessity. both from the Service and the public point of view, for pilots to observe the highest standards in the way they fly their aircraft. The offence of unlawful low flying is particularly serious when committed by a member of the Royal Air Force entrusted as he is with the handling and control of potentially lethal equipment. You should have been aware that you were flying very low and over a potential hazard. Such misconduct involves a significant breach of trust as an officer, as we were told by flying so low you risked your own life and that of others, and of course the consequences of doing that if there had been an accident much worse than the collision are too awful to contemplate. Moreover here, as a direct result of the first offence, your aircraft of course actually collided with a floodlight tower causing significant damage to your own aircraft, which involved, as we have heard, a total cost of replacement of£63,000 ."
'Any person subject to Military Law who, being the pilot of one of Her Majesty's aircraft, flies it at a height less than such height as may be provided by any regulations issued under the authority of the Defence Council except- (a) while taking off or alighting, or (b) in such other circumstances as may be so provided, shall, on conviction by court-martial be liable to imprisonment for a term not exceeding two years or any less punishment provided by this Act. Provided that where a pilot flies an aircraft in contravention of this section on the orders of some other person who is in command of the aircraft, that other person shall be treated for the purposes of this section as having been the pilot of. and flying, the aircraft at the material time.'
"It is also firmly established that the fact that other sections of the Act expressly require mens rea, for example because they contain the word "knowingly," is not in itself sufficient to justify a decision that a section which is silent as to mens rea creates an absolute offence. In the absence of a clear indication in the Act that an offence is intended to be an absolute offence, it is necessary to go outside the Act and examine all relevant circumstances in order to establish that this must have been the intention of Parliament. I say "must have been" because it is a universal principle that if a penal provision is reasonably capable of two interpretations, that interpretation which is most favourable to the accused must be adopted."
'Any person subject to military law who is guilty of any act or neglect in flying, or in the use of any aircraft, or in relation to any aircraft or aircraft material which causes or is likely to cause loss of life or bodily injury to any person shall on conviction by court-martial be liable to imprisonment or any less punishment provided by this Act: Provided that if the offender has not acted wilfully or with wilful neglect he shall not be liable to be imprisoned for more than two years." It is plain therefore that in that section Parliament (i) created an offence which carried a more substantial penalty than section 51, and (ii) created an offence which specifically provides for mens rea and higher levels of punishment if that is proved. A similar situation occurs in Section 44A -the provision under which the second charge against this accused is brought -which provides as follows; '(1) Without prejudice to the generality of section 44 above, a person subject to military law shall be guilty of an offence against this section if he - (a) Wilfully damages or causes the loss of, or is concerned in the wilful material damage or loss of, any of Her Majesty's aircraft or aircraft material, or (b) by wilful neglect causes or allows damage to, or the loss of, any of Her Majesty's aircraft material, or (c) without lawful authority disposes of any of Her Majesty's aircraft or aircraft material, or (d) by any negligent act or omission causes or allows damage to, or the loss of, any of Her Majesty's aircraft or aircraft material, or (e) is guilty of any wilful or negligent act or omission which is likely to cause damage to, or the loss of, any of Her Majesty's aircraft or aircraft material, or (f) during a state of war, wilfully and without proper occasion, or negligently, causes the sequestration by or under the authority of a neutral state, or the destruction in a neutral state, of any of Her Majesty's aircraft. (2) A person guilty of an offence against this section shall. on conviction by court-martial, be liable - (a) if his offence consisted in an act or omission falling within paragraph (a), (b) or (c) of subsection (1) or if it consisted in an act or omission falling within paragraph (f) of that subsection and it is proved that he acted wilfully or with wilful neglect, to imprisonment or any less punishment provided by this Act: in any other case. to imprisonment for a term not exceeding two years or any less punishment provided by this Act.'
"One has to rely on the good sense of Prosecuting Authorities and the overall supervisory role of the courts to avoid such a situation developing. Likewise, of course, the penalty actually imposed in any particular case can reflect the actual degree of culpability involved in a particular case."
