Strangely enough there is a letter in the current edition of Guild (as in GAPAN) News about this very subject. W/Cdr Geoff Collins RAF, who served on exchange in 436 in the Seventies says:
in the 8 mos they were in theatre 436 flew >36k hours, and airlifted 29k tons of supplies and 15k troops, passengers and casualties. 436 is alive and well at Trenton, Ontario, frecently re-equipped with the new C130J.
He recently presented a 436 Sqn badge to the RAF Club.
