I think you might like to check your books. I will refrain from judgmental comments.
We expect to be at a height of 50 feet when crossing the threshold . Altitude is something different.
Approach lights obviously vary but 900 metres is a length you might use.
You would then be around 150 feet above the start of the lights, although given you cannot look straight down, the start of the lights may not be the key issue in CAT 1 minimum weather.
A crossbar at 300 metres (sometimes called a decision bar) giving you horizontal cues to transition visually is a key design element of approach lights and the minimum expected in a simple system.
You can find the data for non normal landing distances in the back of the QRH. I have trouble imagining a situation where you would not break off the approach in this scenario. But as has been said before, in a desperate situation crashing on the airfield at least makes it easier for the emergency services to reach you.
Views differ about birds and radar. Whether it really helps has not as far as I know been proven.
