First post from this aviation geek. I like to keep tabs on the NASA WB-57 (926NA, 928NA) and ER-1 (806NA, 809NA) flights, mostly because they’re so unusual - FL500 is not uncommon. On 27 FEB 08, NASA 928 was a WB-57F out of Ellington field on a routine training hop. Today, it’s a Bomby GlobEx headed to Coronel Enrique Soto Cano AB (MHSC) in Honduras.
Here’s the current flight (in progress at the time of this writing). http://flightaware.com/live/flight/NASA928
A quick check of the FAA database returns empty for 928NA, but 926NA shows up as the “other” WB-57F. NASA has a bucketful of G’s: 2NA and 944NA through 950NA.
(Edited to correct the A/C make/model. I was hung up on the fact that it wasn’t the Canberra I was looking for!)
