You know absolutely nothing about the shuttle. So you must be trolling.

Claims by NASA that a ten-pound chunk of soft water-resistant foam
caused "severe damage to the heat tiles on Columbia's port [left]
wing" are absurd. At the time the foam broke away from the main fuel
tank, shortly after launch, Columbia had a velocity of only 513-mph,
rendering the oblique glancing impact of the soft foam completely
insignificant.
Think about it people, think about it! This is a craft
designed to withstand the impact of minor space debris while in orbit,
and then cope with enormous temperatures during re-entry to earth's
atmosphere. The heat tiles are even designed in such a way that if
you lose a few {and some have been lost in the past], the Shuttle will
easily survive to fly another day.
All we have to do is ignore the NASA fundraisers, ignore
the blatantly forged Israeli picture "proving" that Columbia had
"cracks and a dent" in its left wing, and focus on hard data which
were made available on the actual day of the catastrophe, before NASA
could start changing the ground rules.
Real-time telemetry provides us with the proper sequence
of events, which are as follows: There was an asymmetric 45F
temperature increase in the left wing, reported by heat sensors
located next to the left main wheel bay. Then these sensors failed
completely, followed by failure of those sensors which normally report
the tire pressures of the left main wheels, which are located inside
the left wheel bay. By any reasonable analysis, at this point we have
a serious problem next to, and also inside, the left main wheel bay.
Most probable cause [indicated by the sensors] would be fire.
Next up, the real-time telemetry records sudden and
massive drag on the left wing; drag so incredibly severe that the
emergency retro-rockets fired in an attempt to correct the Shuttle's
attitude. Losing a few heat tiles would produce no significant drag at
all, because they would have already left the craft and be trailing
far behind in its slipstream. Got it so far? But what if Columbia lost
50 tiles, or even more. Exactly how would this affect the space
vehicle during re-entry? Well, there would have been a much steeper
increase in asymmetric temperature than was recorded by the sensors,
but still very little drag, because there is a perfectly streamlined
wing surface existing immediately underneath the tiles.
