Awwww... That loudest of loud T-37 Tweet still around ?
It is called the 6000# dog whistle!
Retired in 2009
Alas, the USAF retired the last of the T-37's in 2009. We almost replaced the T-37 with the T-46:
But kept the T-37 instead until the it was replaced in the 2000's by this plane, the Beechcraft T-6 Texan II:

Looks like the T-37 Tweet was retired from active service on 31 July 2009.
Used to watch the A-37 Dragonfly take off from Willow Grove (PA) NAS in the late 1980s.
