Mistakes made as experts gather information after crash (9)

'mistakes' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'as experts gather information after crash' is the wordplay.
I cannot quite see how this works, but
'information' could be 'i' (common abbreviation for information) and 'i' is found in the answer.
'experts' could be 'aces' (ace is a kind of expert) and 'aces' is found within the remaining letters.
The remaining letters 'fall' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'made' is the link.
