Would I be safe in assuming that what is meant by “reasonable means of preventing an aircraft from being flown” in the Transport Security Act has the same level of “reasonableness” as applied by local police.
That means the standard required is enough security to thwart a casual attack by a thief using nothing more sophisticated than common hand tools. We do NOT have to protect against a determined assault by someone with considerable aircraft knowledge and, for example, a cordless angle grinder because, by definition, such attacks are unstoppable absent Bank levels of security....... or do we? How common is attempted theft of an aircraft anyway?
