Loads of people have either taxied or taken off with concrete lumps tied on.
Somebody did it where I am based, I gather.
Shows how useless those tiedowns are.
hole in someone's garden made by a lump of concrete coming off an aircraft.
No, that was probably the concrete they have to put in the back of a Bonanza to keep the W&B legal with just 2 people in the front
(or maybe some other type
).
