I do have a question

It has been reported that on other shuttle missions that ice and foam have fallen off

Are there any photo's of those times and maybe they could be compared to this one

I know you really can't compare, but I have no idea what this foam looks like ..

Mo1,
The ET insulation is orange-brown.

Previous missions have not had debris this large hitting the orbiter TPS.

Small ice particles can make pock-marks on the TPS under the vehicle. Those photos are countless.
