The airport was built as the first permanent airport serving Trondheim and initially was used for <a href="/wiki/Norwegian_Air_Lines" title="Norwegian Air Lines">Norwegian Air Lines</a>' (DNL) routes which commenced in 1935. Ahead of the 1936 season, the airport was equipped with permanent installations, including wharfs and a small terminal building. In 1937, the airport was used by <a href="/wiki/Wider%C3%B8e" title="Widerøe">Widerøe</a>, before DNL returned the following year. </p><p>During <a href="/wiki/World_War_II" title="World War II">World War II</a>, the airport was taken over by the <a href="/wiki/Luftwaffe" title="Luftwaffe">Luftwaffe</a>, which used the ice on the lake as an airfield. Two aircraft which sank when the ice thawed were raised in 2004.

The aviation club Trondheim Flyklubb reopened the airport in 1967 and remained there until 2013, when the airport was closed, since the airport's existence was incompatible with Jonsvatnet serving as the main source of drinking water for Trondheim. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Trondheim_Airport,_Jonsvatnet&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Construction_and_early_years">Construction and early years</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Trondheim_Airport,_Jonsvatnet&action=edit&section=2" title="Edit section: Construction and early years"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Norway_Post" class="mw-redirect" title="Norway Post">Norway Post</a> took the initiative to start an airline service from <a href="/wiki/Bergen_(city)" class="mw-redirect" title="Bergen (city)">Bergen</a> via Trondheim to <a href="/wiki/Troms%C3%B8_(city)" title="Tromsø (city)">Tromsø</a>, which would allow a letter to travel between Bergen and Tromsø in two days, rather than eight.<sup id="cite_ref-v86_1-0" class="reference"><a href="#cite_note-v86-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> <a href="/wiki/Norwegian_Air_Lines" title="Norwegian Air Lines">Norwegian Air Lines</a> (DNL) received a concessional monopoly on all scheduled air services in Norway from 1935, and the postal service contracted DNL to operate a route to Northern Norway.<sup id="cite_ref-v89_2-0" class="reference"><a href="#cite_note-v89-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Several places were considered, such as <a href="/wiki/Skansen" title="Skansen">Skansen</a>, which was located in the city center on the <a href="/wiki/Trondheimsfjord" class="mw-redirect" title="Trondheimsfjord">Trondheimsfjord</a>.
