A gallon of hydrochloric acid - but described simply as "cleaning fluid"???
There seems to be so much more to this story. Was the passenger detained? What excuse was offered for such an illicit cargo? Is he/she being charged? How could such a material escape detection?
Surely it is extremely worrying when this quantity of a hazardous fluid manages to get through Luton's (so called) security, and the airport's bland statement on its website is woefully inadequate. ("The appropriate authorities were called and identified the substance as a cleaning fluid, which was then contained and cleaned up. London Luton Airport staff worked alongside the authorities to remedy the situation as quickly as possible.")
Don't we deserve a fuller explanation?
