One Vulcan....one time...and one bomb hit on the runway and Gongs all around.
Wow....Golly....Gee Whiz!
Not taking away from the crews who stuck their necks way out to accomplish this but when considered from a realistic point of view....the mission did not accomplish much no matter how one tries to argue it.
Some Harriers used properly could have done much more damage and on a more frequent basis.....perhaps at more risk.
What success the raid had to preventing the Argies from using the runway is more due to the Argies than to the Raid itself. Had they wanted to use the runway....it could have been made right within days if not hours....had they been prepared to do so.
If one studies the timeline of the War....there are probably other factors that caused the Argies to do what they did that were more influential than the Vulcan attack.
