ALSIB mission : wreck of the Consolidated B-24A-CO Liberator (serial 40-2367, cn 19) of the USAAF, which crashed in the Aleutian Islands at Bechevin Bay, Atka, Alaska, on December 9, 1942. (52.03036382, -175.13688310).


Logbook

The first calibration phase of the ALSIB mission can now begin in ROI #1 (Region of Interest #1, in the image) thanks to the successful training of our remote sensing tool.
ROI #1 includes the Seward Peninsula in Alaska and the Chukchi Peninsula in the Chukotka Autonomous Okrug of Russia.
Following the calibration phase, a first automated remote sensing test will be conducted in ROI #2 in the Aleutian Islands.

As a reminder, the ALSIB mission is of major interest to our research on artificial intelligence methods, particularly machine learning and deep learning, for locating missing aircraft wreckage.
The first key factor is geomorphological: the route crosses tundra ("bare land") and taiga (sparse boreal forest), which facilitates visual verification of wreckage identified by radar (SAR).
The second factor is the potentially high density of aircraft wrecks; a single radar image can contain several.
Furthermore, many of these wrecks have remained largely intact for over 80 years, providing an authentic and realistic scenario for studying missing aircraft detection.

Below: under the radar of missing.aero, wreck of the Consolidated B-24A-CO Liberator (serial 40-2367, cn 19) of the USAAF, which crashed in the Aleutian Islands at Bechevin Bay, Atka, Alaska, on December 9, 1942. (52.03036382, -175.13688310).


The training of our remote sensing system reached an important milestone with the observation of the wreckage of Douglas C-47B-35-DK (DC-3) I-TAVI (serial 33225/16477), Aerolinee Itavia Flight 703, which crashed in Sora in 1963. Google Maps
Remote sensing of the wreckage under the canopy is made possible thanks to the latest developments in our Machine Learning algorithm and our calibration and signal processing tools.
The accessibility and stability of the I-TAVI wreckage allows us to collect ground truth data that validates the remote sensing.

Above: Since 1963, the Monte Serra Alta forest has completely covered the wreckage, invisible at optical frequencies (41.76074973, 13.56371247).
Below: Under missed.aero's radar, the wreckage is spotted under the canopy.


Following remarkable collaborative work, on January 26, 2025, missing.aero successfully performed an automatic remote detection of an abandoned aircraft wreck in the Far North.
The aircraft being sought is a Fairchild C-82A Packet (C-119, serial 45-57793, tail N208M), which crashed on January 16, 1965, in Beaver Creek, Alaska, USA (66.48237875, -147.22558932).
The most famous of the preserved Packets, N9071F/45-57814, was nicknamed Ontos (the thing) in Greek, a nickname that later became the emblematic nickname for all Packets.

The target for our test was chosen for several reasons: its high latitude location (66.5°N), its distinctive silhouette, and its historical stability. Indeed, the wreck, abandoned and rarely visited since 1965, provides an excellent benchmark for the experiment.

Above: the accuracy of the remote sensing is breathtaking: 35 cm per pixel.

The missed.aero website made its first flight in the digital sky in the first week of January 2025.
This long-awaited launch was greeted with impatience and curiosity.
Designed to serve the convergence of interests of our researchers and partners, the site becomes a center of information, innovation and inspiration.
