What was the temperature at launch and what was the temp aloft. What was the speed of the package at 80 seconds of launch and the altitude. The photos of the strike show the object pulverizing like a snowball hitting a windshield at speed. If I hit a block of insulation in my car at 100 mph it may break my windshield and kill me but it is not going to disintregrate on impact is it. It looked more like ice to me than than something solid but I'm willing to admit I have the IQ of a burger flipper.
The aforementioned insulation will break and powder from simply dropping it on the floor. It is very fragile when un mounted or protected.
It would probaby not have broken your windshield, but might have cracked it and would have blown into thousands of fragments and dust.IMHO
