Tail-take-off - Yes I agree with your observations about Malcom Pendrill, as he did my Instructors Course photo in 1989. Found this entry online -
Mr Malcolm Pendrill
24 West Street
Reigate
Surrey RH2 9BX (01737) 246576 CHAIRMAN PENDRILL FAMILY HISTORY SOCIETY
But looking at the current Pendrill Family History Society it has a different Chairman now.
You have probably looked through the Rotorspot Register like I did. What confused me was there is a photo of G-BBBP in Post#23, and then 212man said he did his 212 conversion in G-BBP in Post#25. So he must be wrong as I now agree it was PK-HCJ which was written off after suffering a complete loss of tail rotor & inclined pylon on short finals to a staging area NE of Duri.
Registrations can be confusing. What was 5N-AJL (clue - there was actually 2 of them if you believe the internet!).
T4 Risen - The Rogue's Gallery in the White House was only of the later courses that went through there, not the whole Gallery from the 1st Bristow course.
