Also, as seen, foaming just isn't necessary. There are few sparks and unless your airframe is shot full of holes and leaking Avgas (as in WWII where this procedure originated) there is very little risk indeed. Just land off the centreline where the protruding light-housings will rip the structure cruelly and try to ignore the horrible grinding noises. Holding the nose up is so common sense it scarcely merits mentioning, surely?
It also involves very little more thought and skill than any other landing, despite what the experts above may avow, although it certainly concentrates the attention a little. And, as shown above, often (usually?) results in little more than superficial sheet metal damage in smaller types such as the one involved. Coping with little nuisances like this are what pilots are paid for...N'est ce pas?
Even so, nice job fellas!
