Entri pertama sentiasa sumber pin. Keyakinan keseluruhan ialah purata berpemberat bagi sejauh mana setiap rujukan menyokong masa mula dan tamat yang digunakan di atas; sesebuah rujukan diambil kira separuh kurang bagi setiap 180 hari lebih lama daripada yang terbaharu.
This Day in Aviation: '19 February 1982: At Renton Municipal Airport, Boeing test pilots John H. Armstrong and Samuel Lewis ("Lew") Wallick, Jr., made the first flight of the prototype Model 757 airliner'; the Seattle Times[5] also dates it 19 Feb.
Boeing planning document with the 186-seat two-class layout and 255,000 lb takeoff weight.[1]
Flight visited Boeing Field when the 757 had flown twice; Lew Wallick felt "very comfortable" flying formation on the 727 camera plane on the first flight.[1]
The prototype rolled out at Renton on 13 January 1982 with 136 orders from seven carriers; the seven-month test program used the first five aircraft.[1]
Chief test pilot John Armstrong calls it a "perfect first flight" on 19 February, though a design problem later corrected made him shut one engine down; the 375-hour test schedule to December 1982 was met.[1]
Ada yang tertinggal atau salah? Nyatakan dengan kata-kata anda sendiri: pautan yang menyokong pin ini, tarikh mula atau tamat yang berbeza beserta sebabnya, atau fakta yang tiada atau tersilap. AI menyemaknya berbanding sumber pin ini, mencari yang lebih baik, dan menambah mana-mana halaman yang menyokong anda. Sumber pin itu sendiri tetap paling diambil kira. Gambar yang menunjukkan sesuatu yang lain, atau menunjukkannya dengan buruk, turut dilihat, dan dialihkan ke bawah atau diganti.
