GON, it wasn't a KLM plane, it was a Malaysia Airlines flight, MH17. And your mates name is actually spelled Gerry. It was a very sad event, made worse by the lack of acknowledgement or responsibility for downing the aircraft, on the Russians part.

Why didn't you go back to fitting and turning at Hawker-DeHavilland after you did your NS? It was obligatory for businesses to hold job positions open for their employees doing National Service.
QUOTE:
"Under the National Service Act 1964, employers were legally obligated to hold positions open for employees who were called up for compulsory military duty.
Key Details of the Mandate:
Reinstatement Obligation: Employers had to restore servicemen to their previous positions (or an equivalent role) as soon as practicable upon their completion of full-time service.
Terms and Conditions: The returned employee was entitled to the same salary, status, and seniority they would have achieved if they had not been conscripted.
Eligibility Rules: To qualify, the employee typically needed to have been employed by the business for a set period prior to their call-up."
