Parked it there as they went in to pray before heading over to the airport to blow everyone up. the heat started to detonate the bombs.
Doubt it was heat. Middle of winter here. Probably ably 10 degrees Celsius (50F) at most.
Can’t really see this happening in quiet Thornlie. Maybe Armadale (aka Armahole) or Mirrabooka (aka Mozambooka). Friends and family in Thornlie, Forest Lakes and Canning Vale. This would not happen there.
