Just seen footage of the two Spanish planks going under the bridge. 1st one was established in level flight at about 15 foot and seemed well controlled. The second one dived under and seemed to clear the bridge by very little. 1st was as safe as it could have been, the 2nd was madness.
Demonstrates that flying under bridges can be safe (ish) when the pilot sets about it in the right way and how dangerous it is when a pilot just seems to blag it without a great deal of fore thought.
