You must be ingesting copious amounts of genetically altered foodstuffs and ensconced in tin foil. Your statement is bald of truth as it applies to the return of a shuttle for landing.
Due to heating during re-entry into the atmosphere, any re-entry vehicle is surrounded by plasma, which, oversimplified, is superheated gas to the point where it is ionized. The plasma, which is electrically conductive, prevents any RF traffic between the RV and the ground. No voice communication, no telemetry. When the velocity of the RV is reduced to the point where friction heating no longer produces plasma, RF communication can be re-established. This has been noted since the Mercury program. Not tinfoil, simply physics. Now if the shuttle was past the re-entry regime where there is plasma just before the failure events, then I stand corrected. If not, you are as technically illiterate as the rest of the media loons including Dan Blather.
