Tubeless Tires: the call-a-friend solution to flats?

My first experience with Vittoria AirLiner road inserts:

More importantly, my scariest flats have been in the mountains above 25mph.

First was with Conti GP4KSII tires and tubes at about 35mph:

rudely interrupted a ~16 minute HC descent (~3200’ / 975m descent).

Tubes :-1: Could have been a total disaster - with tubes or tubeless - but I brought the bike to a controlled stop.

Thats why I use inserts. The safety of tubulars without the hassle.
