What was the ‘machine’ you were using ?

Diesel eh,,,,,,,,i reguarly dispose of aircraft and believe me it is highly flammable,,,ok not as bad as petrol but certainly more volatile than diesel,i have had a centre tank of a 747 which was drained of fuel,,just a bit of residual in the pipes,,one swipe with the machine and up she went ,,a fairly big fire enough to take my oxygen away,luckily manadged to reverse out in time
