kedves Pista,
   beazonosítottam egy még nagyobb problémát 1942. január 3-án, amit az
I-58 (utódja megtervezése után I-158) szintén rosszul oldott meg. keresd
dátum szerint itt:
   http://www.combinedfleet.com/I-158.htm
   aztán ott van a kaiten-probléma is... az is "nagyobb", az sem
kinematikai.
feladatodat megoldatlanul meghagyom angolt tanuló diák kollégáinknak.
kapcsolódó gondolataidra kíváncsi vagyok. (valószínűleg senki sem tudja,
hogy a képzett, egyebekben sikeres, a kinematikában kétségtelenül jártas
legénység hogyan, miért vétette el a két jókora cirkálót. talán Te?
   ha félreértettem valamit vagy ha bántana levelem, kérem bocsáss meg
nekem. baráti üdvözlettel: bagoj
