OK, what the hell has happened to the Brits?

So you're depending upon the terrorists not learning a secret.

How would they learn it?

There are dozens of ways. It's sort of like solving an equation - from
the knowns you can derive the value of x. The IRA (nothing to do with
pensions, but republican terrorists in Northern Ireland used to spy
quite frequently to find the identity of their enemies and kill them),
and the IRA weren't on suicide missions. Someone determined enough to
face the certainty of death will probably be even more determined.

A brute-force way of doing it would be to have two terrorist cells on
board. The first one begins the hijack. The sky marshall takes charge
and does his job *instantly identifying himself and where he keeps his
gun* to the second cell. The second cell then swing into action some
time later, first seizing control of the sky marshal and his weapon, and
then continuing with their plan. And now they are armed with a gun.

Since flight attendants are allowed on the flight deck, where there is a
crash axe available, what security vetting are we doing of flight
attendants? What does the sky marshal do when an FA incapacitates the
crew with a crash axe and locks the reinforced cockpit door behind him?
