This can be easily be done during the "Memento" fragile delivery near the headquarters safehouse (The Lair). This is a very easy and short delivery, one of the first you will come across. Always skill roll when doing jumps or dropping down somewhere. The skill roll will ensure a soft landing and keep the package safe. There is a package symbol displayed at the top of the screen. If you see it taking damage, you must restart the delivery (let time run out or kill yourself and it will automatically restart).
