Although I like this one...SONIA and MARK (and myself) with their friend WITEK who was also a pilot and trained the US MILITARY in gliding at the private airport near to HOTELU ASYSTENCKI...he was 'management' at GIG EXPERIMENTAL MINE INSTITUTE...and we are all just about to go down into the mine, to see the 'bomb and detonator' - as well as the bag of 'dust' (see previous notes upon how an explosion occurred at the BIRD'S EYE CUSTARD factory - a massive one - just one spark and whole clouds of dust were ignited)...before it was detonated...we were taken above ground to a 'control tower' which quickily filled up with JAPANESE BUSINESSMEN...to see what was rather like watching a nuclear explosion out of a train tunnel...a huge bang - so painful it almost took my ears off - even in that tower and with ear-muffs on...a ball of fire that filled the entrance of the tunnel as it shot out into the countryside...and a massive MUSHROOM cloud of smoke floated upwards...
