Two compilations from RAE Aberporth combined on one reel.
I. "Thunderbird Firings 1975" (titled). Five Army (Royal Artillery) firings of the Thunderbird Mk 2 missile, apparently the whole of the 1975 campaign. Tracking on each firing is for approximately five seconds, ie separation plus two or three seconds. Not all the tracking is good, and No 5 suffers an early break-up.
II. Compilation showing early failures of the original "big three" missiles - Red Duster, Red Shoes and Seaslug.
