Well Roger,

I'm typed rated in the Falcon 50 and 900. First of all, they don't have
"them." There is only one reverser on a 900, on the center engine. NONE
of Dassaults landing performance charts are predicated on using
reversers--NONE. If they landed on your 3800 ft field you can be SURE
their computed landing distance data assured a safe landing without
reversers. BRAKES STOP JETS!!!! Further, the 50 and 900 series Falcons
are excellent short field jets because their wing design with leading
edge devices enable them to use short fields. Not their reverser!

Best,
Karl
