Getting it rammed in your face by someone with no skills is one thing, but if you're dumb enough to up at a capped field, you deserve to be vulched.
Exercise some patience, up from a field that's further away, grab some alt, burn your fuel load down, and use your E. If there's no base within reasonable flying distance grab a Wirble. If the VH is down, sit in the tower and watch the fireworks, or roll a WW in from the spawn.
