Lendab lennuk taevas. Lendab l\u00e4bi pilve. Kontaktist pilvega v\u00f5ib lennuki keresse koguneda staatiline elektrilaeng, eriti kui pilv sisaldab j\u00e4\u00e4kristalle, \u00fclijahtunud veepiisku v\u00f5i tolmu.<\/p>\n

See negatiivne laeng, mille kandjad on elektronid, ei ole tavaliselt otseselt ohtlik, kuid v\u00f5ib tekitada sidekrabinaid ja antennis\u00e4demeid, ilusama poole pealt aga p\u00fcha Elmo tulesid.<\/p>\n

Tegu on \u00fcsna tavalise h\u00f5\u00f5rdeelektri n\u00e4htusega, mis ilmneb ka n\u00e4iteks kommikarbilt \u00f5hukese pakendikile eemaldamisel.<\/p>\n

Et laengut lennuki keres igaks juhuks siiski kahandada, on lennuki tiibade tagumistele servadele tihtipeale kinnitatud erilised piklikud v\u00e4ljaulatuvad vardad, et elektronid saaksid nende teravatest tippudest h\u00f5lpsamini \u00f5hku tagasi liikuda.<\/p>\n

N\u00fc\u00fcd sekkub sesse ilusasse m\u00e4ngu aga r\u00fchm mitme maa, peamiselt Hollandi teadlasi, peamiselt astronoome, kelle raadioteleskoobi vaatev\u00e4lja on m\u00f5nikord juhuslikult sattunud ka m\u00f5ni lennuk. Teadlased on neid juhuseid kasutades end m\u00f5nikord ka lennukivaatlusega l\u00f5bustanud.<\/p>\n

<\/p>\n

Olaf Scholten Groningeni \u00dclikoolist ja ta kolleegid kirjutavad ajakirjas Nature Communications<\/a>, et nende vaatlusandmete j\u00e4rgi ei v\u00e4ljugi suurem osa elektronidest lennuki kerest mitte neile just nimelt selleks otstarbeks tiibadele paigaldatud varraste kaudu, vaid neid tulvab v\u00e4lja peamiselt hoopis mootorite piirkonnast ja sabaotsast.<\/p>\n

Nii paistab olevat raadiolainete j\u00e4rgi, mida elektronide liikumisel kiirgub.<\/p>\n

Teadlased kirjutavad, et nende vaatluste t\u00e4psus on umbes 50 sentimeetrit. See n\u00e4itab muu hulgas sedagi, kui t\u00e4psed on t\u00e4nap\u00e4eval astronoomide vaatlusseadmed.<\/p>\n

Lennukeid vaadeldi raadioteleskoobiga LOFAR, mille antenniv\u00f5rgustik paikneb peamiselt Hollandis, kuid osaliselt ka muudes Euroopa maades.<\/p>\n

Lennuk, mida vaadeldes n\u00e4htus avastati, osutus lennuandmeid tagantj\u00e4rele uurides Hollandi lennufirmale KLM kuuluvaks Boeing 777-ks. Vaatluse ajal lendas ta umbes kaheksa kilomeetri k\u00f5rgusel.<\/p>\n

Vahejuhtum n\u00e4itab, kuidas teadus v\u00f5ib m\u00f5nikord pakkuda p\u00e4ris ootamatuid leide p\u00e4ris ootamatus valdkonnas, lennukiinseneridel on siin aga ehk isegi ka teatav m\u00f5tlemise koht.<\/p>\n
