Hee hee. Good job I don't knock on anybody's door.
Ref the gas explosions. They are hugely impressive to see from the air. Saw one a couple of years ago whilst just north of Penrith - it looked like an atom bomb. Huge mushroom cloud that seemed to last for ages, and definitely went well above our level. Can't remember what radius the NOTAM had given (5 miles?), but I remember thinking had you been on the edge of that exclusion zone at the time it went off, you'd have cacked yourself big time.
