Noted comment within article: “The seaplane, badly damaged, was towed to shore.”

It is unlikely any substantial portion of this aircraft remains in the lake. But I would expect that as a result of crashing nose first into the water at a high rate of speed (from a fall that originated at 4000 ft) at least some of the wreckage remains in the lake.

General Info:
As Boeing became recognized as the leading designer of military aircraft, it received in 1923 a Navy order for the trainer Model 21, or NB-1 and NB-2. The company delivered 70 Model 21s in 1924 and 1925.

Variants

  • VNB-1 – prototype (1 built)
  • NB-1 – original production machine with Lawrance J-1 radial engine (41 built)
  • NB-2 – production machine with Wright-Hispano E engine (30 built)
  • NB-3 – one NB-1 with lengthened fuselage and modified empennage to improve handling, and Hispano-Suiza E engine.
  • NB-4 – one NB-1 converted similar to NB-3, but with Lawrance J-1 engine.

The NBs were produced in two batches; the first (NB-1) were powered by radial engines and the second by war-surplus V-8s still in the Navy’s inventory.
