Cov neeg coob coob tau dim ntawm 6 tus neeg tuag, tiam sis ob tug tom qab tau thov los ntawm cov dej khov ntawm cov dej Mon.
Dab tsi tshwm sim tom qab ob lub lis piam tom qab ntawd yog ib qho ntawm Pittsburgh qhov tsis tseem ceeb tshaj plaws tsis muaj tseeb.
Ua li cas rau B-25 tus neeg tua neeg?
Txoj Kev Hais Txog Dab Tsi rau B-25 Bomber
Hauv ob lub lis piam tom qab qhov kev sib tsoo, tshawb nrhiav lub dav hlau tau ua, tab sis tsis muaj qhov pom ntawm B-25 puas tau pom. Kev xav txog lub dav hlau disappearance yog plentiful thiab tseem tham txog thoob plaws hauv Pittsburgh.
Muaj qee leej xav tias lub dav hlau tau nqa ib daim card zais ntawm nuclear riam phom, paj roj, Mafia nyiaj, lossis txawm Howard Hughes. Cov xwm txheej ntawm cov xwm txheej tau tshwm sim. Ib zaj dab neeg tau hais tias, "Pua pua tus tub rog tau nqis mus rau qhov chaw tsoo thiab tau kaw qhov dej, lawv tuav cov ntug dej ntawm cov dej thaum lub nkoj txav los thiab rub tus neeg thau khoom mus rau saum npoo av. mus rau ib qho ntawm lub zos steel mills thiab melted down. " Variations ntawm cov dab neeg nrog rau lub dav hlau raug tws ntawm ntug dej thiab tsheb thauj tawm, hem rau tim khawv ntawm ntug dej, txawm tias zaj dab neeg ntawm ib tug neeg 7 tus txiv neej uas raug rho tawm ntawm tus dej.
Zaj dab neeg yog zoo li ib tug yeeb yaj kiab tsim khoom lag luam yog xav txog kev ua yeeb yam txog kev tsis paub txog ntawm Mitchell Ntsuj Plig Bomber.
Kev paub tsis meej ntawm B-25 muaj kev tiv thaiv rau ntau tshaj 50 xyoo. Txhua ob lossis peb lub xyoos, ib qho chaw hauv ntawv xov xwm hauv zos ntawv xov xwm txog kev sib tsoo, thiab cov neeg ua tim khawv tshiab tau tawm los nrog "zaj dab neeg tiag tiag."
Qhov Tshawb Nrhiav Tseem Ceeb rau B-25 Bomber
Cov kev tshawb nrhiav tseem tseem yog, coj los ntawm ib lub koom haum hu ua pawg B-25 Recovery Group los ntawm ib qho kev sib txuas ntawm cov tib neeg uas muaj lub siab nyiam rau aviation, nkoj, dej hla, Pittsburgh, thiab, ib txwm muaj kev paub zoo dua qub.
John Uldrich, ib tug ua lag luam thiab tswj xibfwb, tam sim no qhia nyob rau hauv Suav teb, ua tus coj pawg. Nws muaj keeb kwm nyob rau hauv sonar technology, tau koom nrog ntau cov kev tshawb nrhiav thiab rov qab los ntawm lub ntiaj teb, thiab tau siv sij hawm ntau hauv Pittsburgh.
Bob Shema, ib tug Pittsburgh haiv neeg thiab pab pawg neeg Cov Kev Ua Haujlwm, yog tus kws tshaj lij dej. Nws coj qhov kev nkag siab tob txog ntawm Mon River thiab kev kawm nrog sonar kev lag luam rau pab neeg. Steve Byers yog ib lub tuam txhab computer hauv Sennex nyob rau sab qab teb toj, thiab Matt Pundzak yog tus kws pab tswv yim los ntawm Virginia. Matt, Steve, thiab John yog txhua tus neeg tsav tsheb.
Cov pab pawg pib ua cov ncauj lus kom ntxaws thiab kev tshawb fawb rau hauv txoj hmoo ntawm B-25 xyoo 1995. Lawv ua tib zoo sib koom tes ua tim khawv thaum hmo ntuj ntawm kev sib tsoo thiab nws cov limtiam tom qab, tau siv ntau pua lub sijhawm uas muab los ntawm cov ntaub ntawv los ntawm tsoomfwv thiab pejxeem, thiab xam phaj cov kws tshaj lij ntawm txhua yam ntawm cov dej hauv lub Mon, mus rau hauv dej hauv qab, mus tsim thiab kev tsim kho ntawm Mitchell B-25 bomber.
Lawv txawm tshawb xyuas cov qauv siv nyob rau hauv Mon Mon River rau simulate qhov twg cov dej yuav tau noj lub dav hlau.
Qhov tshwm sim ntawm tag nrho cov kev tshawb fawb no? Bob Shema, pawg Pabcuam Kev Ua Haujlwm, nws ntseeg hais tias lawv tau pom qhov chaw zaum kawg ntawm lub davhlau ntawd. "Peb zoo siab tias peb yuav muaj peev xwm daws tau qhov kev paub no," nws hais. Txawm li cas los, lub dav hlau twb tsis tau nyob ntawm lub caij nplooj zeeg ntawm xyoo 2016.
Tus Vaj Ntsuj Plig Yuav Poob Chaw Nyob Qhov Twg?
Shema ntseeg hais tias lub dav hlau tab tom zaum li ntawm 10 mus rau 15 kauj ruam ntawm silt nyob rau hauv 32 taw ntawm cov dej cia li tua ntawm Cov Noog Tsaws. Cov Noog Tsaws Tshaj los ntawm cov qub J & L hlau zeb sab hnub poob ntawm Glenwood choj ntawm mile marker 4.9. Nws yog ib zaug khi-tawm chaw rau cov barges.
Thaum nug tias kev ntseeg siab npaum li cas nyob rau hauv qhov chaw no, Shema ntsig txog qee cov pov thawj uas lawv tau sau txog tsib xyoos dhau los.
"Muaj pua tus neeg qhov muag tau ua tim khawv rau kev sib tsoo," Shema hais. Lub dav hlau tau mus rau sab hnub tuaj ntawm Glenwood Choj (ua ntej Homestead High-Level Choj) mus txog tus dej. Shema mus piav qhia tias tus dej tau khiav ceev ceev hnub ntawd. Tsib ntawm rau lub nraub qaum uake tau nce mus rau saum nruab ntug ntawm lub dav hlau thaum nws ntws los hauv qab. Tsis ntev tom qab ntawd, lub dav hlau tau tu siab. Plaub tug neeg ua haujlwm tau txais kev cawmdim, thiab ob lub cev tau zoo rov qab los, poob deg.
Lub Corps ntawm Engineers thiab Fabkis tus Neeg Cog Tseg dragged tus dej dua tom qab tsoo. Shema tau hais tias qhov xwm txheej ntawd tau hais tias lub Corps hooked li cas lawv ntseeg tias yog lub dav hlau ntawm lub dav hlau. Nyob rau hauv tus txheej txheem ntawm coj nws mus rau saum npoo, li cas los xij, tus thauj tog rau hauv tawm, thiab lub dav hlau rov qab rau hauv dej. Tom qab ntawd, lawv tau ua dua lwm yam, tiam sis hauv kev sim coj mus rau qhov chaw, 2 "cable cable snapped." Shema tau hais tias muaj cov duab ntawm no khiav lag luam, thiab cov duab ua yeeb yam siab nrawm thiab cov nta dej, muaj hnub no. "Peb paub qhov tseeb thaum qhov chaw dav hlau tau kawg pom," Shema hais.
Nws ntseeg hais tias lub dav hlau tau zoo nkaus li snagged thawj zaug lawv sim mus rub nws, tab sis, thaum ntawd nws slipped tawm, nws poob mus rau hauv ib qho qhib gravel qhov ntawm Cov Noog Tsaws. Tom ntej ob zaug, thaum cov cables snapped, Shema xav tias lawv tau qee yam dab tsi. Cov Noog Uas Tsaws Chaw nyob hauv tsev mus rau ib qho chaw qub uas muaj cov dej khov nab kuab. "A 2" tuab hlau hlua yuav tsum tshaj 31,000 phaus ntawm kev quab yuam kom tawg, "Shema hais tias." Ib tug B-25 nyhav ib nrab tawm. Ib qho ntawm ob peb yam hauv cov dej uas yuav ua tau yog tias qub kev lag luam dej khov nab kuab. "
Sib tham cov neeg tim khawv
Tsis tas li ntawd, yog tias lub dav hlau twb tau rub tawm lawm, thauj khoom ntawm tsheb ciav hlau los yog cov nkoj, thiab spirited down tus dej, yuav tsum muaj ib txhia tim khawv. Shema tau siv 30 xyoo ua haujlwm rau hauv cov dej thiab tau tham rau ntau pua tus neeg uas nyob rau ntawm tus dej ntawd hmo ntawd. "Nws tsis muaj cov neeg tim khawv pom tseeb," Shema said.
Nws hais txog zaj dab neeg ntawm ib tus neeg tim khawv uas lawv xam phaj leej twg hais tias nws saib cov tsiaj ntawm lub nkoj, dub suits thiab flippers, tua tag nrho lawv lub teeb thiab mus rau hauv dej. "Cov dej kub yog 34 degrees, dej tau ntws li 5 caug dej, dej nyab yog 3 feet, ib qho dej nyab nyob rau hauv 50 lub, qhov teeb meem rau cov neeg ua haujlwm yog 155 lb Mark 5 dhia seev cev. Qhov kawg tshaj plaws uas tus neeg mob yuav tsum muaj nyob rau hauv cov xwm txheej ntawd, nws yuav tsis tshee, qhov no tsis yog tim khawv tseeb.
Lwm tus neeg lawv tau tham yog tus poj niam uas lees paub tias nws tus txiv yog tus neeg mob uas tshem tawm ntawm lub cev "xya lub cev". Nws piav tias qhov no yog qhov kev zam txim rau nws tsis tuaj tom tsev hmo ntawd.
Tom qab siv ntau pua xuab moos uas dhau los ntawm cov ntaub ntawv, kev xam phaj cov neeg tim khawv, thiab kev soj ntsuam xyuas cov qauv nrog sim ua kom pom deb npaum li cas lub dav hlau tau taug kev nqes mus, Shema ntseeg tias lub dav hlau tseem nyob hauv dej.
Sonar Mapping lub Mon
Hauv xyoo 1995, cov pab pawg sib koom ua lag luam ntawm Mon River ze cov noog uas siv cov kev kuaj sab scan sonar. Qhov no paub tseeb hais tias qhov chaw ntawm qhov gravel qhov, qhov sib sib zog nqus qhov tsim ntau xyoo dhau los ntawm 'gravel pirates' leej twg dredged tus dej hauv qab rau gravel. Lawv kuj pom muaj ib qho kev tshav ntuj. Nws muaj lwm qhov duab uas tsaus ntuj uas cov pab pawg ntseeg ntseeg tias yog ib tus neeg tuaj koom lub koom haum B-25.
Kom paub meej tias cov dav hlau qhov chaw, cov pab pawg xav siv hlau txhim kho hlau nplaum. Qhov no yog ib qho khoom siv uas tsis tuaj yeem ua rau ntes tau hlau faus hauv qab lub plua plav thiab lub plab ntawm Mon River. "Qhov cuab yeej no yuav tsum tau muab ib daim duab txog dab tsi nyob rau hauv Cov Tsab Noog Tseg," hais tias Shema. Thaum lawv pom zoo qhov chaw, lawv yuav coj mus kuaj ntawm tus dej hauv qab thiab tshawb xyuas lawv kom paub tseeb tias cov hlau pom muaj zoo tib yam li uas siv rau hauv kev tsim kho ntawm Mitchell bombers. Tus nqi xauj khoom ntawm cov cuab yeej thiab kev siv zog los siv nws yuav tau li $ 25,000.
Shema muaj kev ntseeg tias lawv yuav nrhiav tau qhov chaw ntawm lub dav hlau, tab sis qhov kev xav ntawm ib qho kev zoo nkauj eerie ntawm Pittsburgh tus neeg tua neeg nce siab tawm ntawm Mon yog tsis ntseeg. "Peb cia siab tias yuav nrhiav tau cov cav ntoo, tsaws iav thiab lub log tsheb - lawv txhua tus tau ua kom tsis muaj teeb meem ... tab sis tas ntawm lub dav hlau - doubtful." Shema kuj hais tias cov dej zoo ntawm cov dej Mon hauv xyoo 1950 yog cov neeg pluag, qhov zoo tshaj plaws. Lub neej expectancy ntawm tej hlau hauv lub Mon cov dej kuab yog 1/3 rau ½ uas yog Allegheny. "Koj tsis tuaj yeem khaws ib lub cav tawm hauv lub thoob txhua xyoo - lub cav yuav tsis muaj pauv nyob rau txhua lub sij hawm." Txhua tus txhuas [ntawm lub dav hlau] yuav tsum tau ploj mus, tshwj tsis yog muaj dab tsi tuaj yeem tiv tau nrog hauv qab, " Shema hais. Plaub dhia dej tau ua nyob rau hauv Mon mus rau hnub tim, tab sis txhua yam lawv nrhiav tau ntoo. "Koj tsis txhob nrhiav hlau hauv Mon," hais tias Shema.
Tshawb nrhiav txog keeb kwm
Pab pawg B-25 Recovery Group ua haujlwm nrog lub koom txoos keeb kwm ntawm Western Pennsylvania (HSWP) thiab Sen. John Heinz Pittsburgh Regional History Center hauv kev sib zog. Ms. Betty Arenth, tus thawj tswj hwm ntawm Keeb Kwm Keeb Kwm Keeb Kwm, nws zoo siab ua ib feem ntawm kev daws qhov kev paub no. "Nws yog ib qho tseem ceeb rau peb tau koom tes nrog Bob [Shema] thiab pawg B-25 Recovery Group - nws yog ib feem ntawm Pittsburgh keeb kwm," "Nws hais tias Arenth.
Shema tau hais tias thaum lawv pom lub dav hlau, cov artifacts yuav muab mus rau Lub Tsev Kawm Ntawv Keeb Kwm. "Thaum peb pom nws, nws yeej yog ib qho credit rau tag nrho cov Pittsburgh rau cov kev pab lawv tau muab rau xyoo."
Thaum nug txog kev sib cav theories, Shema, Pittsburgh ib txwm, nco txog hnub lub dav hlau poob. Nws tau hais tias "Nws yog qhov kawg ntawm 50 xyoo, nyob rau qhov siab ntawm kev sib ntaus ua rog, thiab peb nyob puag ncig ntawm cov chaw nres nkoj, peb xav tias peb cov tub rog yuav tuaj tawm thiab tshem tawm cov dav hlau tsis muaj neeg ua pov thawj." "Peb plaub puas leej tsis muaj peev xwm tau nqis peev ntau lub sij hawm thiab cov khoom siv tseem ceeb rau kev tua tsiaj qus." Vim li cas tus neeg yuav tsum tau tso pa taws, los yog nuclear riam phom rau ib lub dav hlau tsis muaj zog? Lub dav hlau yog Air National Guard dav hlau, tus kws qhia Nws tau ua haujlwm thaum 18 lub hli, nws yog hnub kawg ntawm lub hli, thiab cov neeg tsav nkoj tsuas sim tau lawv lub sijhawm sib tw. "
Shema kaw, "Qhov no dav hlau tsuas khiav tawm ntawm roj".
Txhua tus neeg xav tau kev pab los daws ib qho ntawm Pittsburgh qhov tsis paub ntau tshaj plaws tsis muaj peev xwm ua tau los txiav se tawm ntawm pab pawg B-25 Recovery Group. Lub koom txoos keeb kwm ntawm Western Pennsylvania tau tsim ib qho nyiaj rau pawg neeg. Kev pub dawb, tau muab xa mus rau HSWP tuaj yeem raug xa mus rau qhov chaw nyob hauv qab no:
