I am happy to say that our DC 6 is still running strong. We use wet power on almost every loaded t/o. The ADI mixture adds another 450 HP, and allows another 5000 lbs on take off. Luckily we are able to jettison our load in about 2 secs in the event of an engine failure. Wet power can also be called for on a three engine over shoot. Our company also flies the Convair and they use ADI as well, although in a different mixture as the six. No problems so far...
