It'd be a bit of a short flypast if it only included aircraft in service then that are still in service now.
No Sea Harrier (damn, 'he' will pop up now I've mentioned it, just you see).
No Harrier GR3.
No Victors.
No Vulcans.
No Wasps.
No Wessexes.
No Canberras.
Of course we still have.
A Scout at Middle Wallop?
VC10s
Hercs.
Very aged Sea Kings.
Chinnies (although I believe Bravo November is otherwise engagaed).
Sea Lynx.
Nimrod.
Have I missed any others?
