Slight thread creep but I think it is near enough.
A new glossy hit my desk this week - Eurofighter Review - Issue 1 - 2007.
Inside is contains on page 19 "External fuel tanks, for increased range, are certified for supersonic flight while "wet" air to air refuelling, with the unique fully-retractable refuelling probe, is cleared for all specified customer Tanker types, including "buddy-buddy" refuelling from Tornado aircraft."
Wow, all along I thought external fuel tanks were there to increase drag and reduce the number of available weapons stations.
I guess the unique fully-retractable refuelling probe is an in-house concept and owes nothing to McDonald Douglas or Panavia?
As for buddy-buddy, correct me if I am wrong but Tornado-Typhoon is
not buddy-buddy.
