They will brainstorm the answer step by step reasoning carefully and taking all facts into consideration
All experts will write down 1 step of their thinking,
then share it with the group.
They will each critique their response, and the all the responses of others
They will check their answer based on science and the laws of physics
Then all experts will go on to the next step and write down this step of their thinking.
They will keep going through steps until they reach their conclusion taking into account the thoughts of the other experts
If at any time they realise that there is a flaw in their logic they will backtrack to where that flaw occurred 
If any expert realises they're wrong at any point then they acknowledges this and start another train of thought
Each expert will assign a likelihood of their current assertion being correct
Continue until the experts agree on the single most likely location

The experts reasoning is...
