Eric wondered:
"Can someone tell me the proposed/accepted angle of descent
of the asteroid which formed Meteor Crater in AZ?"
The trajectory of the impacting body was interpreted by Shoemaker
as traveling north-northwest at a relatively low impact angle.
and furthermore:
"Wikipedia has the impactor at 50 meters across,
and velocity at 12.8 km/s. Is this accurate?"
The authors write themeteorite had a velocity in the range of about 13 to 20 km/s,
probably in the lower part of this range and estimated the coherent meteorite diameter
to have been 45-50 m with a mass of 300,000 - 400,000 tons!

of impact conditions (Meteoritics 30-5, 1995, p. 567).
