Re "On a side note, and for continued aviation content, did you know most WW1 aircraft used Castor Oil in lieu of mineral oil because they had it"....
And,
"Breathing this burnt oil caused "flying sickness D" which was later named Tuberculosis"....
The guys and gals at Hood Aerodrome, Masterton, would love to know of this I would reckon - as they fly WW1 replicas, complete with engine replicas of the era, manufactured from 'scratch', and still use Castor Oil as the lubricant.
Something to do with the 'Total Loss' oil system and the temps / pressures of those engines.....
I'm sure that someone from across the 'detch' can elaborate....
Cheers
(I must learn how to spell....)
