*Sigh* Memories.....
My school in St Albans was slap bang beneath the circuits to both Hatfield and Radlett.
Back then (1960's) Hatfield was turning out Tridents, to be seen flying there were also 125's, Comets, the odd Sea Vixen and trials (I believe) Hunter.
Radlett wasn't as busy, but was ripe with Heralds (I especially remember the Malaysian Air Force ones), the odd Victor, and a Hastings used to turn up fairly regularly (well it seemed that way)
Also travelling in to London from Harpenden, the main line ran straight past Radlett and there was a long row of lovely white Victor B1s (I think that was the correct mark) parked in the dispersals right alongside the railway line.
And the first black hangar proudly boasted "Handly Page Ltd" in huge white letters across the doors.
Nice line the Midland - went straight past Hendon too
*Sigh*
