I suspect "ethics" were not quite so fashionable back then...

: Thank you guys for your interest...
: Some research on this Barcelona Spain race Jochen Rindt mentioned
: in the letter, the Heuer racers Siffert, Hill and Rindt were in
: one team.
: I wonder how could Chapman leave Rindt and Siffert in the race
: after the rear wing of Hill has flown off ?

: GRAND PRIX RESULTS: SPANISH GP, 1969
: Spanish GP
: Montjuich Park
: May 4, 1969

: 90 Laps, 3.791 km

: With Madrid having built the Jarama circuit, the ever-competitive
: Catalans decided to revive the old Montjuich Park track in
: Barcelona, which had been used in the early 1930s before the
: outbreak of the Spanish Civil War, and so the Spanish federation
: was forced to alternate the Grand Prix between Madrid and
: Barcelona. Parts of the circuit had been resurfaced and barriers
: built along the perimeter to bring it up to Grand Prix standard.

: In the two month break between the South African GP the F1 teams
: had raced twice - the Race of Champions at Brands Hatch and
: International Trophy at Silverstone. Jackie Stewart had won the
: first for Ken Tyrrell's Matra International while the second had
: gone to Jack Brabham, who was reveling in his new Cosworth
: engines. Lucien Bianchi, who had become a regular F1 racer with
: the Cooper-BRM team the previous season, had been killed testing
: an Alfa Romeo sportscar at Le Mans.

: The entry for the race in Barcelona was as expected with Pedro
: Rodriguez lining up for Reg Parnell Racing, Ferrari fielding
: only one car (Chris Amon) and Piers Courage making his first
: appearance in a World Championship event in a Frank Williams
: Brabham. Lotus (Graham Hill and Jochen Rindt), Brabham (Brabham
: and Jacky Ickx), McLaren (Bruce McLaren and Denny Hulme), Matra
: (Stewart and Jean-Pierre Beltoise) and BRM (John Surtees and
: Jack Oliver) were unchanged with Jo Siffert racing as usual in
: his Walker-Durlacher Lotus.

: Rindt set the pace in qualifying and took pole position ahead of
: Amon and Hill. Stewart and Brabham shared the second row with
: Siffert, Ickx and Hulme on row three.

: At the start Rindt led the field away and quickly built up a lead
: over Amon, while Hill moved to third ahead of Siffert. On the
: ninth lap Hill's rear wing failed as the Lotus crested the rise
: after the pits. He crashed heavily but emerged uninjured. Eleven
: laps later the same thing happened to Rindt. The leader crashed
: into Hill's abandoned car and overturned. The Austrian was
: fortunate to emerge with only a few cuts and bruises and a
: broken nose. The crash left Amon in a commanding lead over
: Siffert, although he disappeared on lap 31 with an engine
: failure, leaving Stewart in second place, over half a minute
: behind Amon. Brabham was third with Ickx fifth. On lap 52
: Brabham's race ended with an engine failure and five laps later
: Amon's Ferrari V12 seized. This left Stewart in the lead with
: Ickx trailing him, although the Belgian's rear wing fell apart
: on lap 64 and he dropped to third while a new one was fitted,
: leaving McLaren to take second. In the closing laps Ickx
: suffered rear suspension failure (probably due to the downforce
: from the rear wing) and he retired, leaving Beltoise to finish
: third.
