WHBM

Forgotten his name, but the BAC sales manager for The Americas in the 1960s-70s was a onetime test pilot for Bristol Aircraft, merged into BAC, and may well have been on this trip. I say "may well have" because the trip, to Brazil/South America, appears to have been wholly designed to suit a French trade fair etc. It was always notable that whereas in Britain the Concorde project was always presented as joint Anglo-French, in France it was only ever mentioned as French. The same still applies to Airbus nowadays.

There's a prominent transport writer in Britain, Roger Ford, mainly writes about rail but is also a PPL (and thus shared a flying club cafe with WHBM), who has "10 golden engineering principles" about major projects, witty but generally true. One of the ten is "Never get into a joint venture with the French".
