Types believed to be excluded:
- all single-engine fighters operating in pairs or lacking radar
- Betty ASW
- Betty Ohka
- Emily/Mavis (encountered multiple unit flights of one of these types around Truk without issue)
- Lorna (not spotted but non-operational prior to 1945)

My impression is that all of the other identified all-weather ASW contacts we've had post-Truk were of a single type, most likely Judy. Not sure we've seen a single Kate or Jill; the latter being the obvious culprit and so undoubtedly exonerated long ago.

If the CTDs are not induced by a specific plane, could it be a combination of diving, turning, and a radar alert? In three of the four specific cases I recall, we were following a recently plotted course involving multiple turns over a relatively large area (Convoy College being the smallest; Bungo-Kii-Suruga the largest) and went to periscope depth upon radar warning of a plane. TC was somewhere between 32 and 250ish, IIRC.

i vote for the ASW Betty. That is the plane that was in the vicinity when i got my CTD.
