Veering off on Beech 18s, BC politician Flying Phil Gagliardi had what may have been the most modified Beech 18, IIRC:
- one-piece windshield
- tricycle landing gear
- single tail
- turboprop engines
I was up close to it once in 1966, but did not learn why he put so much into an old airplane. Granted, in those days some people had small bombers like B-25s as executive aircraft (awkward cabin with wing through fuselage).
And he did use it, all over the province as Minister of Transport.
