Thanks Peter, I had forgotten how large Zagami really was. So much for going strictly by memory. That would make an upward limit much higher for initial size especially if one uses 50% ablation loss. I personally don't think it is that high but that is still a approximately up to a hefty 40kg original mass. Zagami was high in glass and probably pushing the limits of mass and acceleration without turning completely to glass-- else vaporizing. I just looked and there were 4 or 5 Martians falling between 7 and 18 kgs and those lie outside the theoretical argument I just put forth. No matter how it is tweaked, an upward limit of 7 kg initial is obviously wrong.
As to the press release, it claims "US record" size so I don't think this is the Tissint mass of Anne's letter.
Regards,
Elton
