Subject: How much survives entry?

From the Handbook of Iron Meteorites, Volume One, by Vagn F. Buchwald
states: Results of studies indicate that 1-4 mm is lost per second of
flight. Ablation loss is probably confined to the part of the
trajectory
that is luminous. The lengths of the luminous trajectories range
from about
40 km (Bruderheim) to about 700 km (Orgueil). Ablation can occur for
periods of around 4-seconds to over one minute. The total amount of
material lost ranges from a few percent to 100% with an average
velocity of
10 km/second. This is not a direct quote but has been edited.
