Hi B737NG,
I do not agree with the 25ft that some Desk flyer decide,
That's the was the way it was in the 80s. Only the UK CAA permitted us to do NO DH approaches - everywhere else we were required to have a mini DH and be able to see at least one runway centre line light before continuing to Land.
On the GA - we thumped the runway with the gear before climbing away, so we would have squashed whatever was beneath us hiding the centre line light anyway.
