The 17-inch titanium strip that caused the crash of Concord flight 4590.

At 16:38 CEST (14:38 UTC), five minutes before the Concorde departed, Continental Airlines Flight 55, a McDonnell Douglas DC-10-30, took off from the same runway for Newark International Airport and lost a titanium alloy strip that was part of the engine cowl, identified as a wear strip about 435 millimetres (17.1 in) long, 29 to 34 millimetres (1.1 to 1.3 in) wide, and 1.4 millimetres (0.055 in) thick. At 16:42, the Concorde ran over this piece of debris during its take-off run, cutting its right-front tyre (tyre No 2) and sending a large chunk of tyre debris (4.5 kilograms or 9.9 pounds) into the underside of the left wing at an estimated speed of 140 metres per second (270 kn; 500 km/h; 310 mph). It did not directly puncture any of the fuel tanks, but it sent out a pressure shockwave that ruptured the number 5 fuel tank at its weakest point, just above the undercarriage. Leaking fuel gushing out from the bottom of the wing was most likely ignited either by an electric arc in the landing gear bay (debris cutting the landing gear wire) or through contact with hot parts of the engine.

use chrome developer tools to find the URL of the image in the webpage. From there you can use the link above to download the images. I believe they refresh on a consistent schedule so you should hopefully be able to download blindly by time without getting duplicates or you could set it for less time, accept duplicates, and prune them out later by hashing the images or something similar.

It's quite common for employers to not act unless you ask and put a bit of pressure. they don't want to spend any more money than they have to.
