Imagine this scenario…………………

A man of Middle East appearance stuggles up the steps to the viewing gallery at Heathrow, he carries a large bag containing a rocket , over his shoulder is its launcher,
“Are you alright there mate?” asks an aircraft spotter, “Here, let me give you a hand” as he and 3 other spotters help the man with his rocket launcher,
“Thank you,” says the Arab looking man,
“You’re welcome,” says the spotter,
“It’s a nice day,” says the arab as he sets up his launcher, “been much in?”
“No,” says the spotter, “been quiet today,” he says, “supposed to be an Israeli government jet in later though”
“Really?” says the Arab.
“Anyway,” asks the spotter, “What you after?”
“The Israeli jet,” he says,
“Nah,” says the spotter, “you’d get a better view over by Hatton Cross, and a better shot at it!”
” Oh thankyou ,” says the Arab as he dismantles the launcher, “You English are so helpful”

It seems to me that our security forces are naive enough to think this would actually happen
