I have updated my Decay Watch page with the final notices for #2129 and 
#5281 - summaries follow.
_____________________________________________________________________
Object: #2129 = 66- 26 B = P-35-15 Thor Altair rocket

Final analyses:
Source   Prediction made    Predicted decay at      Latitude Longitude
                UTC                UTC                  deg      deg
SpaceCom   May 10 22:19     May 10 20:58 +-1h        15.2 N   120.5 W
SatEvo     May 11 18:25     May 10 21:00 +-20m       15.9 S   126.9 W

Final elset:
P-35-15 r                                        152 x 134 km
1 02129U 66026B   02130.80350191  .33650100  30641-5  43769-3 0  8322
2 02129  98.1362 238.7780 0014147 284.4823 205.7739 16.48623635924628

Note: The final elset has this running 2.7 sec early against my
final pre-decay prediction. My new prediction for the start of
the final orbit is:
P-35-15 r                                        134 x 122 km
1 02129U 66026B   02130.84217008 1.20625903  31761+2  74053-3 0 98324
2 02129  98.1332 238.8285 0009196 284.3217  75.5763 16.54260986924634
I estimate that this decayed southbound over the SE Pacific.

Final elset:

Note: The above elset shows this running 16 sec early against my
previous prediction. I put the decay northbound over southern
Brazil near the end of this orbit.
