Today is without a doubt the windiest day we've seen up here in the
northeast in quite a few months... METARs all around NYC are reporting
anywhere from 15 - 25 kts, gusting anywhere from 30 - 40 kts. Some of
the spreads between standing winds and gusts are around 20 - 25 kts, so
a typical C-172 pilot would have to adjust approach speed by around 10
- 13 kts using the half gust factor method.

Me personally, today is a day I stay nice and safely on the ground. Yet
I've noticed a lot of PIREPs in the vicinity - C-172s, Mooneys, etc,
reporting low-level windshear, urgent pireps for moderate to severe
turbulence, and one guy even reported he whacked his head in some bumps
at 6000 feet:

PIREP 15:57Z 10/29/06
ABE UUA /OV FJC360010/TM 1557/FL060/TP M20P/TB SVR/RM HIT HEAD ON
CIELING

My question to you all: why would anyone in a spam can even attempt
flight on a day like this?
