I wasn't there but a friend who lives at the airport relayed this to me that happened a few days ago:
While attempting to start a russian radial,having the air start system on it, the tank pressure was depleted. Well,they did not have a high pressure tank of air like in a scuba tank available, sothey thought they would try some oxygen from a welding tank. It is about the samehigh pressure too, right?
The result from what my friend relayed to me was the explosion brokesome pieces of the engine rear case. So no flying that day.
The lesson here is: don't use pure oxygen near anything oily, like a radial engine!
