A year from now, the RAF’s workhorse warplane will begin to be phased out as the first of the F35 Lightnings which will replace it land at Marham.

Between now and then, the Tornado and its top gun crews will continue training sorties from the Norfolk base over the surrounding countryside and further afield.

Both air and ground crews admit they have ground fond of the Tonka, as the jet is nicknamed.

Many of today’s generation of air force personnel weren’t even born when the Tornado first entered service more than 40 years ago.

The 21st Century aircraft which will replace it is a state of the art stealth fighter which can take off and land vertically.

More than £250m is being spent preparing Marham for its arrival next summer, when 617 Sqn - aka the Dambusters - will be the first to fly it operationally.
