Taiwan's airspace was once again buzzing with activity this weekend as Beijing decided to add to the general feeling of worsening geopolitical tension by staging the largest incursion into the rogue island's airspace since October.

Sunday's incursion included 39 warplanes, mostly advanced fighter jets, the largest number in a single day since China dispatched 56 bombers and fighters and spay planes into the ADIZ on Oct. 4.
