There, you are, in your office, and suddenly, your canopy blows off, and there you are at 30,000 feet and -40° without pressurization.

This us not how you want your day to end:

The Israel Air Force has grounded its fleet of F-15 fighter jets after an incident last week in which an F-15’s canopy, the transparent enclosure over the cockpit, dislodged while the aircraft was flying at 30,000 feet, requiring the crew to make a harrowing emergency landing.

The Israel Defense Force Spokesperson’s Office said that at that altitude, with temperatures of minus 45 degrees Celsius (-49 degrees Fahrenheit) and strong wings, the crew was in danger. The commander of the air force, Amikam Norkin, has ordered a halt to all training flights with the aircraft pending an investigation.

The army released sound recordings of the incident in which shouting is heard followed by the pilot, who has been identified as Capt. Y, telling the ground: “Coming in for a landing at the nearest base without a canopy. Please confirm.” The plane’s navigator, 1st Lt. R., then asked the pilot if he was all right. “Yes, everything is all right,” he replied. The navigator then confirmed that he too was all right. The pilot was asked to slow his speed and then said: “We have no problem getting to base.”

The crew underwent a medical exam following the incident and were found to be in good condition.

If that had been me, I would have gone to pieces so fast that there would have been a risk of shrapnel.
