It sounds like the old days of the One-Eleven requirements to ensure barrels of demineralised water were available anywhere in the network that you flew. A right nause. I remember standing not too far behind a Tarom One-Eleven taking off from an elevated runway one day and getting utterly soaked as the water injection ejected streams of water in a field of spray about 100 feet behind the aircraft when the throttles were opened up. Aah, the joys. You don't get that nowadays....
