Right! Be sure to put on your landing lights in the tunnel!

and honk your horn for luck!

Lordy, no, if you are the one that had that Helio Courier that was at OSH,
what, two years ago?

For those who missed it, he had TRAIN horns, with bleed air from the turbine
engine, powering it!

I was spinning like a top, out on the taxiway (flagging planes at an
intersection), trying to locate the crash truck that was surely going to run
me down! g

Can you imagine a set of horns like that, going off in a tunnel??? :-)
