possible telemetry interference/interpolated data

It appears that this sonde lost signal briefly a little after an hour
into the flight at 18:36:42 (altitude approx 17 km.  Signal was recovered,
but it is possible that the signal was from a different sonde - temp and
RH data appear to be interpolated in the interval from 17 to 20 km.  I
would treat all data above 17 km (after 18:36:42) as questionable.
