The Bundeswehr has produced a nice video of its Tiger combat helicopters practicing taking off for a mission within 30 minutes after the alarm has sounded. The last minute of the video shows two Tigers taking off from Mazar-e-Sharif 25 minutes after the alarm and landing a few minutes later.
The helicopters are covering the German withdrawal of its contingent of NATO's International Security Assistance Force (ISAF).
The pioneer years of aviation included both successful and misguided efforts to make the number of safe landings approximate to the number of takeoffs. Here are some notable examples on both sides of that record.
